[osol-help] Right Alt Key on Opensolaris

[Yogi]

I just installed the latest OpenSolaris, am very excited by using it, 
the looks and feel is just like Ubuntu.  However I encounter a problem 
(or feature!) is that, the Right Alt Key is not working!  How to fix it 
to act the same as the Left Alt Key, for example R-Alt-F will also open 
the File menu on Firefox.
