so I installed Mandrake 9.1 (changing over from Redhat 7.2) recently and have tweaked it all out, but I still can't find where you can tell the system how to react to a ctrl+esc or a ctrl+alt+del

I'm using strictly KDE 3.1.0 and the Redmond Behavior, and i want to set a ctrl+alt+del to bring up the 'task manager' and a ctrl+esc to bring up the K menu. The way it is now is a ctrl+esc brings up the 'process table- KDE system guard' and a ctrl+alt+del brings up the 'end session' dialog where you can logout reboot or restart

any ideas where this is? I seem to remember what i want being default behavior under Redhat 7.2 or a control panel where you could set it.
