Ok, but the original problem still remains.

A KAccel sends only a signal if the key is pressed, but not if the key
is released.
I could compare the key of the key event with the accel key. But since
key bindings can have modifiers (shift...), this will not work.

Hmmm, a intelligent user will not choose modifiers, but I don't want to
get mails that the ships cannot rotate any more :-)

Any possibility to prevent this?
Any more ideas?

I am making my game more kde compliant at the moment (toolbar, xml-gui,
actions, kdialogbase...), so I looked for a solution to get rid of the
game key configuration dialog.

Greetings, Andreas
