+
+MacVim supports swipe, pinch, and rotate gestures.  The swipe gesture can be
+used to navigate back/forward in the help (try it!).  Currently no other
+gestures are set up by default.
+
+Each gesture generates a Vim pseudo key according to the following list:
+
+		    *<SwipeLeft>* *<SwipeRight>* *<SwipeUp>* *<SwipeDown>*
+	Generated when swiping three fingers across the trackpad in a
+	horizontal or vertical direction.
+
+		    *<PinchIn>*	  *<PinchOut>*
+	Generated when moving two fingers together or apart in a pinch
+	movement.  Note that the keys are generated continuously as the
+	fingers move, not only when the gesture has finished.
+
+		    *<RotateCW>*  *<RotateCCW>*
+	Generated when rotating two fingers in a clockwise (CW) or
+	counterclockwise (CCW) direction.  Note that the keys are generated
+	continuously as the fingers move, not only when the gesture has
+	finished.
+
+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
+
+See the section on |key-mapping| for more help on how to map keys.
