In KDE I always used the Win+Tab combination to switch between virtual desktops, but in KDE 3.5 that doesn't work. Instead of the list of Virtual Desktops it just randomly switches between 2 desktops.

More than than, I can't assign Win+Tab to anything. I tried assigning it to a couple of other functions to test it but it keeps on doing the same thing.

This happens in a KDE 3.5 I compiled from source, and another one I installed with Slackware packages, so I guess it's a bug, but is there any way to fix this? It's one of the shortcuts I use most.

well since KDE 3.5 is still new, most of us won't use it till the bugs are worked out
you may need to look for the .config file that handles keyboard shortcuts and edit it directly........ look around in
