Key down events in which Ctrl, Alt, or Command is held are immediately sent off to Vim instead of to interpretKeyEvents:. This is an attempt to bypass Key Bindings in Cocoa, since some key bindings cause several doCommandBySelector: messages to be sent (which means the key gets repeated). This fixed the CTRL-O bug in insert mode.
