Subject: 23.1; (elisp)Motion Events: Incorrect event description
Date: Wed, 11 Nov 2009 10:31:45 -0800

The node says:
 
 Emacs sometimes generates "mouse motion" events to describe motion of
 the mouse without any button activity.  Mouse motion events are
 represented by lists that look like this:
 
     (mouse-movement (POSITION))
 
   The second element of the list describes the current position of the
 mouse, just as in a click event (*note Click Events::).
 
   The special form `track-mouse' enables generation of motion events
 within its body.  Outside of `track-mouse' forms, Emacs does not
 generate events for mere motion of the mouse, and these events do not
 appear.  *Note Mouse Tracking::.
 
This is incorrect, AFAICT. (mouse-movement (POSITION)) should
instead be (mouse-movement POSITION).  The value of POSITION is
itself a list.  This is an example value of a motion event:
 
(mouse-movement (#<window 10 on *info*> mode-line (256 . 332) 9231031
(#(" (elisp) Motion Events" 9 22 (face mode-line-buffer-id help-echo
"mouse-1: scroll forward, mouse-3: scroll back" mouse-face
mode-line-highlight local-map (keymap (mode-line keymap (mouse-3
. Info-mouse-scroll-down) (mouse-1 . Info-mouse-scroll-up))))) . 12)
82181 (31 . 155) nil (7 . 12) (8 . 16)))
