Multimedia IR Remote question

[CaptainZap]

Hey guys,

Just got the remote in the mail and I've plugged it and it worked right out of the box, however the only thing I can't find is an information button (the one that gives you a menu similar to right clicking something in windows - I did try to enable mouse control and try the R button which should work but doesn't do anything), and there are plenty of buttons which don't do anything so should I use this guide to map it ?
I can see there it talk about how to create a whole remote but I only wish to edit/add one button, does anyone know the file I would need to edit ?
Also another thing I've noticed is that fast forward doesn't work with the current xbmc build ? Do you encounter this as well ?

Thanks.
