I know that in Elementary ctrl+alt+del means Log Out.
What I am looking for is an equivalent to windows ctrl+alt+del which activates Task Manager, so that I can close/shut down frozen task?
I know that one can use ctrl+alt+F1 to get to console (ctrl+alt+F7 to get back to GUI) but that doesn't help me much... ?
Sometimes ctrl+F4 seem to kill some active windows? but it doesn't work when things freeze...?
So what's the best way of handling things like this in Elementary?
