           Summary: Support to map a mouse button to emulate double-clicks
           Product: xorg
           Version: unspecified
          Platform: PC
        OS/Version: Linux
            Status: NEW
          Severity: enhancement
          Priority: P5
         Component: Input/Mouse
        AssignedTo: xorg-bugzilla-noise at freedesktop.org
        ReportedBy: pixelmonkey at pixelmonkey.org


Double left clicking is used all over the typical graphical desktops, i.e.
Gnome, KDE, etc.  Many people have mouses with more than three (or "five")
buttons.  In addition to left, middle, right, and the wheel scrollers, many
modern mice include thumb buttons and other extra buttons.  One in particular,
my new Evoluent Vertical Mouse 2 (www.evoluent.com - an ergonomic mouse flipped
on its side to reduce wrist and shoulder strain) features two extra buttons. 
Using the Windows driver, one can assign these buttons to just about anything. 
By default, the fourth button is assigned to be "double click," i.e. you can
click anything with the fourth button and the driver will emulate a double left
click.  For ergonomic reasons, this feature is very valuable, as it reduces the
amount of clicking one must do by a significant percentage.

It would be nice to get this kind of functionality into an X server.  I tried
looking at the documentation for imwheel, but unfortunately they only allow one
to map mouse events to keystrokes.  One Debian developer told me the only way to
get true support for this would be a modification to the x server.  Thus this
feature request.

I would love to attack this problem myself but I have nearly no experience
hacking XFree86 or XOrg.

I am open to any questions, elaborations, or debate.  Thanks.
