In firefox, gaim, etc...
Using Ctrl-Page Up/Down only works with the left Control key. Using the right Control key works with Page up but not with page down.
I submitted this to gaim-bugs, they suggested I post here.
Steps to Reproduce:
1. Open firefox
2. Open a couple tabs
3. Ctrl-Pgup/Pgdn with both Ctrl
Using xorg-x11 6.8.2-r1
worksforme. If you could try 184.108.40.206, I'd appreciate it. Also output of `setxkbmap -print` could be useful.
Both control keys work for me in Both Firefox and Mozilla. Have you verified
that both of your control keys actually work? Anyway this is two months old so
maybe it should get closed if the reporter doesn't respond that (s)he still has
the problem. And the people on the sourceforge tracker link say that it works
for them too.
Waiting for more info.
Embarassingly, I have found out this is a hardware bug with my keyboard. Sorry
about that :-p
