A request for support of the extra back/forward buttons you find on some mice. 

Reproducible: Always



Expected Results:  
Ability to move back and forward with extra mouse buttons like alt+left/right does

I'm not really sure how else to say it if these mice probably aren't that common, but it's a very handy feature so here it is for your consideration. I think these mice are referred to sometimes as "5 button mice" and many are configurable through software on Windows, but X11 seems to commonly map these buttons as some of it's universal back/forward events. Two applications with support for this that I can think of are Firefox 3 and Konqueror.
