I've also noticed this in Firefox, where right-alt + left-arrow
doesn't go back.  I've not yet bothered to find a fix for that, but
you might check to see if it's the same problem that I have, where the
right Alt key is showing up as a "ISO Level 3 Shift" key, rather than
"Alt_R".  From a terminal, run "xev", then press and release the right
alt key once.

I get the following output from that, which shows that the key name is
"ISO_Level3_Shift":

KeyPress event, serial 29, synthetic NO, window 0x3200001,
    root 0x52, subw 0x0, time 2882806124, (380,-80), root:(492,428),
    state 0x10, keycode 113 (keysym 0xfe03, ISO_Level3_Shift), same_screen YES,
    XLookupString gives 0 bytes:
    XmbLookupString gives 0 bytes:
    XFilterEvent returns: False

KeyRelease event, serial 32, synthetic NO, window 0x3200001,
    root 0x52, subw 0x0, time 2882806196, (380,-80), root:(492,428),
    state 0x90, keycode 113 (keysym 0xfe03, ISO_Level3_Shift), same_screen YES,
    XLookupString gives 0 bytes:
    XFilterEvent returns: False

I have two similar systems running edgy, one a fresh install and the
other an upgrade from dapper.  I wasn't sure if it was a hardware
difference (the newer one, a Thinkpad T60p, shows this problem, the
older one, a Thinkpad T40, does not), or a small configuration
difference between a clean install and an upgrade.  I'll try to
compare the two in the next day or so to see if there is an easy fix.
