translating mouse clicks

translating mouse clicks

[r3jsel]

I have a trackball with four buttons which emacs sees as buttons
mouse-1, mouse-3, mouse-4, and mouse-5.  I would like emacs to
treat mouse-4 clicks as though they were mouse-2 clicks.

Googling finds suggestions to try

(global-set-key [mouse-4] [mouse-2])
(define-key key-translation-map [mouse-4] [mouse-2])
(keyboard-translate 'mouse-4 'mouse-2)

but none of these work for me.

Doing the first or second and clicking the mouse-4 button causes
emacs to complain that "mouse-yank-at-click must be bound to an
event with parameters"

Doing the third causes emacs to complain that mouse-4 should be an
integer.

(This is with a relatively recent version of CVS emacs on MS Windows
from nqmacs.sourceforge.net, GNU Emacs 22.0.50.2.)

Can anyone suggest a method that works?

Thanks,
David

Binding mouse-4 to the same binding(s) as mouse2?

Since you have a modern Emacs you could try to determine with grep-find 
in which non-global modes mouse-2 is re-bound ... to bind mouse-4 too!

This essentially makes mouse-4 a keyboard macro which,
when executed, doesn't carry the proper associated events.
There are 2 things you can do with global-set-key.

(global-set-key [mouse-4] (lookup-key global-map [mouse-2]))

But you would need similar commands for shift, control,
meta, shift-control, shift-meta... versions of mouse-4.
And maybe down-mouse-4 ... as well depending on how many
variations of the key you wanted to remap.

A consequence of doing it this way is that it's static.
Once the global-set-key is done re-assignment of mouse-2
won't change what mouse-4 does.
The other way would be to write a function and map it to
all the mouse-4 events, like above.  The function would
look up and called the mouse-2 event currently in effect.

The doc seems to carefully exclude mentioning mouse events
concerning these methods (and function-key-map too).  I
wouldn't expect them to help based on the doc I looked at.

I think it's reasonable to expect the second to work (and it's reasonable for
Emacs to mishandle the first and last).  Please file a bug report with
M-x report-emacs-bug.

Thanks to everyone for their help.  On Stefan's suggestion I've
submitted a bug report on this.  In the mean time, I'm using
variations on rgb's

  (global-set-key [mouse-4] (lookup-key global-map [mouse-2]))

as workarounds.
