1) Are you sure the alt-key on your keyboard is still working? I've had
keys quit working before... It's easy enough to test as part of the
second possibility, however.
2) The keyboard shortcuts may have been changed. Try kde settings
(labeled system settings even tho they're mostly kde, not system, but
anyway...), common appearance and behavior, shortcuts and gestures,
global keyboard shortcuts. Once there, change the dropdown to kwin, and
look at the walk thru windows related settings.
You can change a setting by clicking on it, then on custom, then on the
configure button beside it, which will then take input. If it's already
set there but you want to test your keys for #1, try clicking on one
without a shortcut (so you don't mess up an existing setting). You can
hit alt, ctrl, win, shift, as modifiers, and they'll show up on the
button, waiting for the key that's to be modified. If alt doesn't show
up when you hit it, kde's not sensing the alt-key any longer. Probably
either a broken keyboard or a changed X keyboard mapping.
3) You can actually see what X is detecting by installing if necessary,
then running from a konsole window, a little applet called xev. When
it's active, any key you press or any mouse movement should generate
output in the konsole window you ran it from, telling you what X
detected. If you press the alt key, you should see the output with the
keyboard mapping for the alt key, etc.
4) It's possible you activated the international settings. In
particular, with some mappings, the right alt key is remapped to
different functionality. That's why on some keyboards it's labeled AltGr
or similar. I've never messed with that so can't describe it, but have
read about it. Xev will let you see what the system says the keys are
outputting, tho, and you can compare what it says about the left and
right alt keys.
