{Vi does not have a GUI}

==============================================================================
1. MacVim differences					*macvim-differences*

One of the goals of MacVim is to make Vim behave like a proper Mac OS X
application.  For this reason MacVim behaves slightly different from other GUI
ports of Vim.  Most of the modifications are provided in the system gvimrc
file; you can quickly open this file and look at it yourself by typing: >
	:tabe $VIM/gvimrc
Note that this file will be overwritten each time you update MacVim, so it is
best to keep your own modifications inside "~/.gvimrc".

							*macvim-windows*
There is some confusion regarding the term "window" in MacVim since it means
one thing to Vim and another to MacVim.  A "window" in Vim is what opens up
when you type ":sp", whereas a "window" in MacVim is the GUI window which
contains the text view, scrollbars, toolbar and tabline.  To avoid confusion,
the former is referred to as a Vim-window, whereas the latter is simply called
a window.

							*macvim-encoding*
It is not possible to modify 'termencoding' in MacVim; this option is forcibly
set to "utf-8".  The option 'encoding' also defaults to "utf-8" (as opposed to
"latin1" in the other GUI ports).

Note: UTF-8 can represent all characters defined in Unicode, which includes
all characters in all other standard encodings, so it should be perfectly safe
to edit files in any encoding while 'encoding' is set to "utf-8".  Of course,
you may need to set 'fileencodings' to auto-detect the encoding of the files
you edit, or force the detection with |++enc| on the command line.

However, if you are editing files that use multiple encodings (container
formats like MIME or Unix mbox files) or no standard encoding (binary data,
see also |edit-binary|), you may want to prevent MacVim from re-encoding the
file at all. In this situation, you will need to set both 'encoding' and
'fileencodings' to a simple single-byte encoding such as Latin1 so that when
the file is read into memory, the original bytes are left untouched.

							*macvim-shift-movement*
Text editors on Mac OS X lets the user hold down shift+movement key to extend
the selection.  Also, pressing a printable key whilst selecting replaces the
current selection with that character.  MacVim can emulate this kind of
behaviour (by providing key bindings and by setting 'keymodel' and
'selectmode' to non-default values) although it is not enabled by default.  To
make MacVim behave more like TextEdit and less like Vim, add the following
lines to your "~/.vimrc" (not .gvimrc) file: >
	if has("gui_macvim")
	  let macvim_hig_shift_movement = 1
	endif
<
							*macvim-drag-n-drop*
Dragging files and dropping them on a window opens those files in tabs in that
window, unless Vim is in command-line mode.  In command-line mode the names of
the files are added to the command line.  Holding down modifier keys whilst
dragging is not supported.

If a file is dropped on the Dock icon, it is always opened in a new tab
regardless of the mode Vim is currently in.  The same holds if you
double-click on a file in the Finder.

The "Open files from applications" preference in the General preference pane
gives more options on how dropped files should open, in case tabs are not
desired.

							*macvim-default-menu*
The default menu in MacVim has been changed to conform better with the Apple
Human Interface Guidelines (HIG).  At the moment this breaks the localized
menus, so only English menus are supported.

Note: The menus are a work in progress.  If you know something about the HIG
and want to contribute to MacVim you could do so by making the menus better.

							*macvim-window-title*
The default window title does not include the argument list because it looks
really bad once you start using tabs.  For example, dropping two files, then
dropping two more, and switching back to the first tab would cause weird
strings like "((3) of 2)" to appear in the window title.

							*macvim-tablabel*
Tab labels only show the tail of the file name to make the tabs more readable
when editing files in deeply nested folders.  Add the line "set guitablabel="
to your .gvimrc file to revert back to the default Vim tab label.

							*macvim-options*
These are the non-standard options that MacVim supports:
	'antialias'	'blurradius'	'fullscreen'
	'fuoptions'	'macligatures'	'macmeta'	'macthinstrokes'
	'toolbariconsize'	'transparency'

							*macvim-commands*
These are the non-standard commands that MacVim supports:
	|:macaction|	|:macmenu|

							*macvim-find*
Whenever you search for something in Vim (e.g. using "/") the search query is
copied to the OS X "Find Pasteboard".  The idea is that if you search for
something and switch to another application, then you can hit <D-g> (or <D-G>)
to repeat the search in the new app.  The same feature works if you search in
some app, switch to MacVim and hit <D-g>.

Note that the command |n| is not the same as <D-g>.  The former will repeat
the last search made in Vim, whereas the latter searches for the string on the
OS X Find Pasteboard using the action findNext: (see |:macaction|).

The <D-g> key equivalent is a great way to bring a search from one window to
another in MacVim.  Simply search for something in one window (using "/") then
switch to another (e.g. with <D-`>) and hit <D-g> and the search will be
repeated in the new window.

					*macvim-backspace* *macvim-delete*
The 'backspace' option is set in the system vimrc to make the delete key
behave in a more familiar way to new users.  If you dislike this non-default
behaviour, then add the line "set backspace&" to your "~/.vimrc" file.

==============================================================================
2. Starting MacVim					*macvim-start*

The easiest way to start MacVim is by double-clicking its icon in the Finder,
but most users will probably prefer to use the Terminal.  First some Finder
related ways of starting MacVim are described, then Terminal is discussed.
Note that you can put MacVim anywhere on your hard drive, but in this help
file it is assumed that you have put it inside your /Applications folder.

MacVim automatically registers itself as an editor of several standard file
formats.  This enables you to double-click a file to open it with MacVim (if
it is not associated with another program), or to right-click a file to bring
up the "Open with" menu.  You can also drag and drop files onto the Dock icon
to open them in tabs in a new window, or you can drop them in an already open
window to open the files in tabs in that specific window (it is possible to
have files open in e.g. splits by changing the "Open files from applications"
option in the General preference pane).  Finally, you can use Mac OS X System
Services to open files in MacVim, see |macvim-services|.

There are essentially two ways to start MacVim from Terminal: either call the
Vim binary with the -g switch >
	/Applications/MacVim.app/Contents/MacOS/Vim -g file ...
or use the "open" command (this method can not be used to pass parameters to
Vim) >
	open -a MacVim file ...
The advantage of using the latter method is that the settings relating to file
opening in the preferences panel are respected, and files open instantly if
|Quickstart| is enabled.

To save yourself from having to type the entire path to the Vim binary each
time you start MacVim, you could create an alias such as >
	alias gvim='/Applications/MacVim.app/Contents/MacOS/Vim -g'
and add that to "~/.profile".

Note: Do NOT call the MacVim binary inside the app bundle to start MacVim.

							*mvim*
A more flexible way to start MacVim is to use the shell script "mvim" which
comes bundled with MacVim.  Put this script in a folder in your path and then
simply type "mvim" to start MacVim.  This script will try to find MacVim.app
in various typical folders such as >
	~/Applications              ~/Applications/vim
	/Applications               /Applications/vim
	/Applications/Utilities     /Applications/Utilities/vim
If you would rather put MacVim.app in some other directory then that is also
possible, simply set the environment variable VIM_APP_DIR to whatever folder
you have placed MacVim.app in.

The "mvim" script can be symlinked to in order to start up MacVim in different
modes as follows (assuming you placed "mvim" in "/usr/local/bin"): >
	* Diff:		ln -s /usr/local/bin/mvim mvimdiff
	* Read-only:	ln -s /usr/local/bin/mvim mview
	* Ex:		ln -s /usr/local/bin/mvim mex
	* Restricted:	ln -s /usr/local/bin/mvim rmvim
If the symlink destination starts with "m" (or "g"), Vim will start in GUI
mode.  Removing the initial "m" from the above destination names makes Vim
start without the GUI.  (In the last case, the destination name can be
"rmvim", "rgvim" or "rvim".)

Note: Starting MacVim by creating a symlink to >
	.../MacVim.app/Contents/MacOS/Vim
with 'ln -s' does not work.

Once in terminal Vim it is possible to start MacVim by using the following
command:
	:gui [++opt] [+cmd] [-f|-b] [files...]
Note: Forking ("-b") currently does not work.

							*Quickstart*
Quickstart ensures that new windows open instantaneously e.g. when <D-n> is
pressed.  This feature can be enabled from the Advanced preferences pane (it
is disabled by default).  Note that this setting does not affect the speed
with which windows open when using the |mvim| command.

Note that any changes to runtime files that are kept in a non-standard
location (i.e. not in ~/.vim) will not be picked up for the first window that
opens after any changes.  Also, there are some issues related to reading and
writing of the |viminfo| file which can lead to the command line history
appearing to be lost (as well as any other information stored in the |viminfo|
file).  For example, if you open a window, edit some files then close the
window, then the next window that opens will not have the same command line
history as the window you just closed (however the next window you open will).
For these reasons Quickstart is disabled by default.

						*odbeditor* *external-editor*
MacVim can act as an 'external editor' for Mac OS X applications that support
the ODB Editor Protocol (or the 'external editor' protocol).  Each application
has different ways of configuring this option, check the application's
documentation.  Once configured properly MacVim can be used to open files in
such an application.

A technical note: MacVim handles file open, modified and closed events.  In
the open event the FTok and Burl parameters are parsed (the latter is ignored
at the moment though).  In the modified and closed events the Tokn parameter
is sent back to the server application.

==============================================================================
3. Preferences				    *macvim-prefs* *macvim-preferences*

Some settings are global to the MacVim application and would not make sense as
Vim options.  These settings are stored in the user defaults database and can
be accessed via the "MacVim.Preferences..." menu item.

							*macvim-user-defaults*
Not all entries in the user defaults database are exposed via the preference
panel, usually because they should not be changed by the user under normal
circumstances.  These options can still be changed with the "defaults" command
by opening Terminal and typing >
	defaults write org.vim.MacVim KEY VALUE
Check the man page on "defaults" for more information on this command as well
as general information regarding Mac OS X user defaults.

Here is a list of relevant dictionary entries:

KEY				VALUE ~
MMCellWidthMultiplier		width of a normal glyph in em units [float]
MMDialogsTrackPwd		open/save dialogs track the Vim pwd [bool]
MMFullScreenFadeTime		fade delay for non-native fullscreen [float]
MMLoginShellArgument		login shell parameter [string]
MMLoginShellCommand		which shell to use to launch Vim [string]
MMNoFontSubstitution		disable automatic font substitution [bool]
MMNoTitleBarWindow		hide title bar [bool]
MMShowAddTabButton		enable "add tab" button on tabline [bool]
MMTabMaxWidth			maximum width of a tab [int]
MMTabMinWidth			minimum width of a tab [int]
MMTabOptimumWidth		default width of a tab [int]
MMTextInsetBottom		text area offset in pixels [int]
MMTextInsetLeft			text area offset in pixels [int]
MMTextInsetRight		text area offset in pixels [int]
MMTextInsetTop			text area offset in pixels [int]
MMTexturedWindow		use brushed metal window (Tiger only) [bool]
MMTranslateCtrlClick		interpret ctrl-click as right-click [bool]
MMUseMouseTime			use mousetime to detect multiple clicks [bool]
MMVerticalSplit			files open in vertical splits [bool]
MMZoomBoth			zoom button maximizes both directions [bool]

As an example, if you have more than one mouse button and would wish to free
up Ctrl-click so you can bind it to something else, then the appropriate
command is: >
	defaults write org.vim.MacVim MMTranslateCtrlClick 0

If you wish to restore all user defaults to their starting values, open
Terminal and type: >
	defaults delete org.vim.MacVim
<
							*macvim-login-shell*
Applications opened from the Finder do not automatically source the user's
environment variables (which are typically set in .profile or .bashrc).  This
presents a problem when using |:!| to execute commands in the shell since e.g.
$PATH might not be set properly.  To work around this problem MacVim starts
new Vim processes via a login shell so that all environment variables are set.

By default MacVim uses the $SHELL environment variable to determine which
shell to use (if $SHELL is not set "/bin/bash" is used).  It is possible to
override this choice by setting the user default MMLoginShellCommand to the
shell that should be used (e.g. "/bin/tcsh").  MacVim tries to make the shell
a login shell by prepending argv[0] with a dash.  If you use an exotic shell
and need to pass it a parameter to make it a login shell then you can set the
user default MMLoginShellArgument (e.g. to "-l").  Finally, if the "bash"
shell is used, then "-l" is automatically added as an argument.  To override
this behaviour set MMLoginShellArgument to "--".

==============================================================================
4. Special colors					*macvim-colors*

The colors in MacVim are defined in two dictionaries inside the "Resources"
folder of the application bundle (MacVim.app/Contents/Resources).  It is
possible to add more colors by modifying these files.  Color names are case
insensitive when accessed from Vim, but in the dictionary they must be
lowercase.

							*SystemColors.plist*
There are only a few system colors that can be accessed from Vim.  These
colors are defined in the dictionary "SystemColors.plist".  This dictionary
stores (key, value) pairs where the key is the name of the color and the
value is an NSColor selector name.

The most useful system colors are: >
	MacSelectedTextBackgroundColor
	MacSecondarySelectedColor
The former is the "Highlight Color" which can be changed in the "Appearance"
section of the System Preferences.  The latter is the selection color used by
a Cocoa application when it is not in focus.

							*Colors.plist*
Apart from the system colors, it is also possible to use the standard X11
color names (see http://en.wikipedia.org/wiki/X11_color_names) which usually
come in a file called "rgb.txt".  MacVim does not have such a file, instead it
keeps these colors in a dictionary called "Colors.plist". The key in this
dictionary is the name of the color and the value is an RGB value on the form
#rrggbb stored as an integer.

							*macvim-colorscheme*
MacVim ships with a custom color scheme that is used instead of the default
Vim color scheme.  The color scheme can be changed with >
	:colorscheme macvim
If you prefer a dark background color, then type >
	:set bg=dark
after having loaded the "macvim" color scheme.

Use the |:colorscheme| command if you want to use another color scheme.  Note
that if you want to set syntax highlight colors manually, then you must either
create your own color scheme or add the line >
	let macvim_skip_colorscheme=1
to your ~/.vimrc (~/.gvimrc will not work).  Otherwise the "macvim" color
scheme will be loaded when the system gvimrc file is sourced and mess up your
changes.

The color scheme uses the system "Highlight Color", which can be changed in
the "Appearance" pane of the System Preferences.  It also changes the
highlight color when a window becomes inactive.

==============================================================================
5. Menus						*macvim-menus*

Menus in Mac OS X behave slightly different from other platforms.  For that
reason two new commands have been added to Vim.  To understand what these
commands do you must first understand how menus work on OS X.

Each entry in a menu is called a "menu item".  With each menu item is
associated: a title, a key equivalent and an action message.  When a menu is
displayed the title is shown on the left and the key equivalent (if any) is
shown on the right.  Key equivalents enable you to access a menu item using
the keyboard instead of having to use the mouse.  When a menu item is clicked
it will send it's associated action message.  Actions can be used to instruct
MacVim to paste some text (paste:), open a new window (newWindow:), etc.
Certain actions are standard throughout OS X which is why MacVim must be able
to set these for each menu item.  (E.g. the menu item "Edit.Paste" must be
bound to the action "paste:" otherwise pasting won't work in dialogs since
that is the action that instructs them to paste something.)

Menus are configured using the |:macmenu| command and the |:macaction| command
can be used to send action messages.

						*:maca* *:macaction*
:maca[ction] {action:}	Send the message "action:" to the first responder.
			The list of allowed actions can be seen by typing
			    :maca <C-d>
			An attempt to send an action not listed here will
			result in an error.  This list is specified in a
			property list file called |Actions.plist|.

						*:macm* *:macmenu*
:macm[enu] {menu} {key}={arg} ...
			Set Mac specific properties for {menu}.  The
			properties that can be set are:
			    action	the action this menu sends
			    alt		"yes" if alternate of previous menu
			    key		the key equivalent of this menu
			This command must be used in a startup file, for
			example in "~/.gvimrc".  It has no effect otherwise.

			For convenience, a menu with "action=name:" which is
			bound to <Nop> will act as if bound to
			":maca name:<CR>".  Thus, if "Menu.Item" is given by
			    :an Menu.Item <Nop>
			    :macm Menu.Item action=name:
			then ":emenu Menu.Item" is equivalent to
			":maca name:".

			The key equivalent is specified with the <D-..>
			syntax.  This is case-sensitive, so <D-a> means Cmd-a
			whereas <D-A> means Cmd-Shift-a.
			Note that key equivalents must contain the Cmd
			modifier flag (<D-..>), and they take precedence over
			normal mappings.
			Use the syntax "key=<nop>" to clear the key equivalent
			of a menu.  This can be used to free up a key
			combination that is set in the system gvimrc so that
			it may be mapped to using ":map".

			Recognised values of "alt" are "0", "no", "1", and
			"yes".  The default is "no".  An alternate menu must
			have the same key equivalent as the previous menu,
			except the modifier flags must differ.  The alternate
			menu is by default hidden and only shows up when the
			modifier is held down.

Here are some examples on how to use these commands:

1. Create a menu item with title "New Window" under the "File" menu, with key
equivalent Cmd-n, which opens a new window when selected: >
	:an 10.290 File.New\ Window <Nop>
	:macm File.New\ Window action=newWindow: key=<D-n>
2. Change the key equivalent to cycle through tabs to Cmd-Left/Right: >
	:macm Window.Previous\ Tab  key=<D-Left>
	:macm Window.Next\ Tab	    key=<D-Right>
3. Create a mapping in normal mode which closes the current tab/window: >
	:map <C-w> :maca performClose:<CR>
4. Free up Cmd-t and remap it to open a file browser in a split view: >
	macm File.New\ Tab key=<nop>
	nmap <D-t> :sp .<CR>
Note: These two lines must be added to .gvimrc else the first line will fail.
The second line is case sensitive, so <D-T> (Cmd-Shift-t) is not the same as
<D-t> (Cmd-t)!

The default menus are set up in "$VIMRUNTIME/menu.vim".  Take a look at that
file for more examples on how to set up menus.  Note: When no window is open a
minimal default menu is used.  The default menu is set up in MainMenu.nib
which resides in "Resources/English.lproj/" folder inside the app bundle.

							*Actions.plist*
Some action messages would not be suitable to call from within Vim, so there
is a dictionary called "Actions.plist" (in the Resources folder of the
application bundle) which contains all actions that may be called.  The key in
this dictionary is the name of the action message (case sensitive), the value
is not used.

Hint: The |:macaction| command supports command-line completion so you can
enter ":maca<Space><C-d>" to see a list of all available actions.

Here is a random assortment of actions from Actions.plist which might be
useful.  

Action				Description ~
fileOpen:			Show "File Open" dialog
findNext:			Search forward using the "Find Pasteboard"
findPrevious:			Search backward using the "Find Pasteboard"
fontSizeDown:			Decrease font size
fontSizeUp:			Increase font size
hide:				Hide MacVim
miniaturizeAll:			Minimize all windows to the dock
newWindow:			Open a new (empty) window
orderFrontCharacterPalette:	Show the the "Special Characters" dialog
orderFrontFontPanel:		Show the Font panel
orderFrontPreferencePanel:	Show the Preferences panel
performMiniaturize:		Minimize window to the dock
performZoom:			Zoom window (same as clicking the green blob)
terminate:			Quit MacVim
zoomAll:			Zoom all windows
_cycleWindows:			Select next window (similar to <D-`>)
_cycleWindowsBackwards:		Select previous window (similar to <D-S-`>)

==============================================================================
6. Toolbar						*macvim-toolbar*

The toolbar in MacVim works just like in the other GUIs (see |gui-toolbar|),
with the addition of two separator items (see |menu-separator|).  You can use
them as follows: >
	:an ToolBar.-space1-        <Nop>
	:an ToolBar.-flexspace2-    <Nop>
The first example creates an empty space on the toolbar, the second creates an
empty space which will shink or expand so that the items to the right of it
are right-aligned.  A space (flexspace) will be created for any toolbar item
whose name begins with "-space" ("-flexspace") and ends with "-"

Toolbar icons should be tiff, png or icns, of dimension 32x32 or 24x24 pixels.
The larger size is used when 'tbis' is "medium" or "large", otherwise the
smaller size is used (which is the default).  If the icon file only contains
one dimension then Mac OS X will scale the icon to the appropriate dimension
if necessary.  To avoid this, use a file format which supports multiple
resolutions (such as icns) and provide both 32x32 and 24x24 versions of the
icon.

Note: Only a subset of the builtin toolbar items presently have icons.  If no
icon can be found a warning triangle is displayed instead.

==============================================================================
7. Dialogs						*macvim-dialogs*

Dialogs can be controlled with the keyboard in two ways.  By default each
button in a dialog is bound to a key.  The button that is highlighted by blue
is bound to Enter, any button with the title "Cancel" is bound to Escape, and
any button with the title "Don't Save" is bound to <D-d>.  Other buttons are
usually bound to the first letter in the title of the button.  There is no
visual feedback to indicate which letter a button is bound to, so sometimes
some experimentation might be required in order to figure out which key to
press.

The second way of controlling dialogs with the keyboard is to enable "Full
keyboard access" in the "Keyboard" pane of the System Preferences (you can
also toggle this on or off by pressing Ctrl-F7).  Once keyboard access is
enabled it is possible to move between buttons with Tab and pressing Space to
select the current button.  The current button is indicated with a blue
outline.

==============================================================================
8. System services					*macvim-services*

MacVim supports two system services.  These can be accessed from the MacVim
submenu in the Services menu or by right-clicking a selection.  For services
to work, MacVim.app should be located in the /Applications folder.  (You might
have to logout and then login again before Mac OS X detects the MacVim
services.)

These are the currently supported services:
	* New MacVim Buffer With Selection: Create a new buffer and paste the
	  currently selected text.
	* New MacVim Buffer Here: Create a new buffer and set the current
	  directory to the file or folder that is selected in the Finder.

The services respect the "Open files from applications" setting in the general
preferences.

==============================================================================
9. mvim:// URL handler				*mvim://* *macvim-url-handler*

MacVim supports a custom URL handler for "mvim://" URLs. The handler is
supposed to be compatible to TextMate's URL scheme as documented at >
	http://blog.macromates.com/2007/the-textmate-url-scheme/.

Currently, this means that the format is >
	mvim://open?<arguments>
where "arguments" can be:
	* url — the actual file to open (i.e. a file://... URL), if you leave
		out this argument, the frontmost document is implied
	* line — line number to go to (one based)
	* column — column number to go to (one based)

For example, the link >
	mvim://open?url=file:///etc/profile&line=20
will open the file /etc/profile on line 20 when clicked in a web browser.

Note that url has to be a file:// url pointing to an existing local file.

==============================================================================
10. Keyboard shortcuts					*macvim-shortcuts*

Most keyboard shortcuts in MacVim are bound to menu items and can be
discovered by looking through the menus (see |macvim-menus| on how to create
your own menu shortcuts, see |cmd-key| on how to map your own commands to
Cmd-key shortcuts).  The remaining shortcuts are listed here:

							*Cmd-.* *<D-.>*
Cmd-.			Interrupt Vim.  Unlike Ctrl-C which is sent as normal
			keyboard input (and hence has to be received and then
			interpreted) this sends a SIGINT signal to the Vim
			process.  Use this shortcut if the Vim process appears
			to have locked up and is not responding to key presses.
			This Cmd-key combination cannot be unmapped.

							*Cmd-`* *<D-`>*
Cmd-`			Cycle to the next window.  On an American keyboard the
			`-key is located under the Esc-key.  On European
			keyboards this key is often adjacent to the left
			Shift-key and it may be not even be marked with "`".
			This Cmd-key combination can only be unmapped via the
			"Keyboard" System Preferences.

							*Cmd-Left*  *<D-Left>*
Cmd-Left		Move cursor to the beginning of the line
			(see |cmd-movement|).

							*Cmd-Right* *<D-Right>*
Cmd-Right		Move cursor to the end of the line (see |cmd-movement|).

							*Cmd-Up*    *<D-Up>*
Cmd-Up			Move cursor to the first line (see |cmd-movement|).

							*Cmd-Down*  *<D-Down>*
Cmd-Down		Move cursor to the last line (see |cmd-movement|).

							*Alt-Left*  *<M-Left>*
Alt-Left		Move cursor to the beginning of the previous word
			(see |alt-movement|).

							*Alt-Right* *<M-Right>*
Alt-Right		Move cursor to the beginning of the next word
			(see |alt-movement|).

							*Alt-Up*    *<M-Up>*
Alt-Up			Move cursor one paragraph forward (see |alt-movement|).

							*Alt-Down*  *<M-Down>*
Alt-Down		Move cursor to the previous paragraph
			(see |alt-movement|).

						*cmd-movement* *alt-movement*
The above mappings involving Cmd/Alt + arrow key are enabled by default in the
system gvimrc file "$VIM/gvimrc".  You can quickly disable all of these by
adding the following lines to your "~/.vimrc" (not .gvimrc) file: >
	if has("gui_macvim")
	  let macvim_skip_cmd_opt_movement = 1
	endif
Note: These are the only key mappings that MacVim makes (not counting menu key
equivalents which are not set up with :map).

See |macvim-shift-movement| if you want Shift to select text when used in
conjunction with the above Cmd/Alt movement shortcuts.

						*cmd-key* *cmd-shortcuts*
Creating key mappings that involve the Cmd key (<D-..> in Vim notation) can
sometimes be slightly involved.  Here are all the things you need to consider:

- Make sure the shortcut is not used by a menu item by looking through the
  menus.  If it is then you need to unbind it before you can map to it.  This
  is described under the help for the |:macmenu| command.
- Bindings to <D-..> are case sensitive: <D-d> is not the same as <D-D>.  If
  you want to map something to Cmd+Shift+d, then you need to use <D-D>, not
  <D-S-d> or <D-S-D>.
- Some command key shortcuts are reserved by Mac OS X and cannot be mapped to
  (e.g. <D-Tab>).  However, some of these shortcuts can be freed up in the
  System Preferences under Keyboard (e.g. Cmd+Space).
- A few command key mappings are set up by MacVim, see |cmd-movement|.

==============================================================================
11. Trackpad gestures					*macvim-gestures*

MacVim supports trackpad swipe gestures.  By default this can be used to
navigate back/forward in the help (try it!).

Each gesture generates one of the following Vim pseudo keys:

						 *<SwipeLeft>* *<SwipeRight>*
	Generated when swiping three fingers across the trackpad in a
	horizontal direction.  The Apple Magic Mouse generates these
	events when swiping two fingers in a horizontal direction.

						 *<SwipeUp>*   *<SwipeDown>*
	Generated when swiping three fingers across the trackpad in a
	vertical direction.  (Not supported by the Apple Magic Mouse.)

You can map these keys like with any other key using the |:map| family of
commands.  For example, the following commands map left/right swipe to change
to the previous/next tab in normal mode: >

	nmap <SwipeLeft> gT
	nmap <SwipeRight> gt

As another example, here is how to switch buffers by swiping left/right: >

	nmap <SwipeLeft> :bN<CR>
	nmap <SwipeRight> :bn<CR>

See the section on |key-mapping| for more help on how to map keys.

==============================================================================
12. International					*macvim-international*

When editing non-English text it may be convenient to keep separate keyboard
layouts for normal and insert mode.  This is supported via the 'imd' option on
Mac OS X 10.5 or later (on 10.4 the 'imd' option support is not as useful as
it only switches between Roman and non-Roman input sources and it has been
known not to work very reliably).

For example: When 'noimd' is enabled (i.e. IM is enabled) the input source is
saved when toggling between normal and insert mode, so you can use a US layout
in normal mode then switch to insert mode and choose a Swedish layout.  When
you go back to normal mode the US layout will be selected and when you enter
insert mode the Swedish layout is selected.  This also works when searching
for text etc. see 'imc', 'imi', 'ims'.

Note that the layout used in normal mode is the layout used when 'noimd' is
set (i.e when IM is enabled).  If you find that MacVim switches to the
wrong layout when going back to normal mode, then select the layout you want
to use in normal mode and type ":set imd" followed by ":set noimd".

==============================================================================
13. Known bugs/missing features				*macvim-todo*

This list is by no means exhaustive, it only enumerates some of the more
prominent bugs/missing features.

- Localized menus are not supported.  Choosing anything but "English" in the
  "International" pane of "System Prefences" may break the menus (and
  toolbar).
- Some Unicode characters are not handled well (e.g. nonspacing marks)
- Sometimes multibyte characters look "too wide", i.e. they overlap the
  following character.  It might help to change 'ambiwidth', or override the
  automatic font substitution by setting 'guifontwide' manually.
- Printing.  As a temporary solution <D-p> creates a PostScript file which is
  then opened in Preview where it may be printed.
- The toolbar looks ugly and is not very useful.

If you find new bugs then please post your findings to the vim_mac mailing
list:							*vim_mac*   >
	http://groups.google.com/group/vim_mac

This is also the best place for making feature requests as well as for asking
general questions about MacVim.

14. Hints						*macvim-hints*

In this section some general (not necessarily MacVim specific) hints are
given.

Scenario: ~
You try opening a bunch of files in tabs but not all files get opened in their
own tab.
Solution: ~
To get around this, set 'tabpagemax' to something big in your .gvimrc file
(e.g. ":set tabpagemax=100").

Scenario: ~
You want to open a file in a tab in an already opened window, but typing "mvim
filename" in Terminal opens it up in a separate window.
Solution: ~
Use the |--remote-tab| switch.  If you have several windows open you might
have to specify which window you want the file to open in by using the
|--servername| switch.  The title of a window usually ends in something like
"VIM" or "VIM3" --- this is the server name of that window.  So to open a file
named "foobar.txt" in a window whose title ends in "VIM3" you would type (the
order of the arguments matters): >
	mvim --servername VIM3 --remote-tab foobar.txt
For more information, consult the |client-server| manual page.

Scenario: ~
You like to be able to select text by holding down shift and pressing the
arrow keys and find the Vim way of selecting text strange.
Solution: ~
See |macvim-shift-movement|.

Scenario: ~
You do not want MacVim to set up any key mappings.
Solution: ~
See |cmd-movement|.

Scenario: ~
Enabling localized menus breaks the toolbar and the menus as well.
Solution: ~
This is a known problem, see |macvim-todo|.

Scenario: ~
When you click the (green) zoom button you want the window to maximize
horizontally as well as vertically.
Solution: ~
Hold down Cmd and click the zoom button.  If you prefer this to be the default
action, then set the user default MMZoomBoth (see |macvim-prefs|).

Scenario: ~
Typing feels sluggish when the cursor is just before a right bracket (i.e.
')', '}', or ']').
Solution: ~
Disable the "matchparen" plugin (see |matchparen|) by typing :NoMatchParen.
If that helps, then you can permanently disable "matchparen" by adding the
following line to your "~/.vimrc": >
	let loaded_matchparen=1
<
Scenario: ~
You want to use MacVim as an editor for some external application.
Solution: ~
If the external application lets you set a program to execute then something
like "mvim -f" might be all you need (the "-f" switch ensures that the "mvim"
script returns only after you close the editor window, otherwise "mvim"
returns immediately). If the external program honors the EDITOR environment
variable (e.g Git does this) then you may get away by adding the following
line to your "~/.profile": >
	export EDITOR='mvim -f'
If you have not installed the "mvim" script in your path you can provide the
path to the Vim binary instead.  Thus, if "MacVim.app" resides in the
Applications folder then you would use the following line: >
	export EDITOR='/Applications/MacVim.app/Contents/MacOS/Vim -g -f'

Scenario: ~
You have set MacVim to open from an external program and when you finish
editing (by closing the MacVim window) you want the external program to regain
focus.
Solution: ~
Use the VimLeave autocommand to hide MacVim when the window closes: >
	au VimLeave * maca hide:
Assuming your external program has a setting for which command to execute to
bring up an editor, you would set that option to something like: >
	mvim -f -c "au VimLeave * maca hide:"
(See the above Scenario for an explanation of the "-f" switch.)

Scenario: ~
You would like to remap Caps Lock to Esc.
Solution: ~
The app "PCKeyboardHack" can be used to remap Caps Lock.  It is available as a
free download from: >
	http://pqrs.org/macosx/keyremap4macbook/extra.html
On some Apple keyboards the Caps Lock key doesn't immediately register and
this makes Caps Lock "drop" key presses.  To work around this problem go into
the "Keyboard" System Preference and remap Caps Lock to Ctrl first (click the
"Modifier Keys..." button).  This trick may also be necessary if the Caps Lock
light turns on/off despite having remapped to Esc.

Scenario: ~
You have problems creating custom mappings involving the Cmd key.
Solution: ~
To bind to a key involving Cmd you use the "<D-..>" syntax.  Many Cmd-key
mappings are already used by the menus so if your mapping doesn't work then
the solution is usually to first unmap the menu binding (see |macvim-menus|,
in particular read the end of that section).  Also see the section on
|macvim-shortcuts| for some Cmd-key combinations which are not used by the
menus but still need to be freed up before they can be used in custom bindings.

Scenario: ~
You can't find the information on MacVim you thought should be in this manual
page.
Solution: ~
Post your question on the |vim_mac| mailing list and wait for an answer.
