+Mouse support with multisel
+===========================
+
+This provides the basic mouse support described in the 'mouse support' patch,
+but against 4.6 (32f2564dbbbf5aeafb7190a3d35066142f34448f).
+
+In addition, multisel is supported via Ctrl-leftclick.
+(i.e. Ctrl-leftclick does for mouse operation what Ctrl-Return does for
+keyboard, as described in the 'multisel' patch; however, the 'multisel' patch
+itself is no longer needed in 4.6 because its functionality has been previously
+merged in and now it's part of the master)
