Thread Subject: control-C programatically?

I want to create a shortcut that when you presses it, cntrl-C (aborts the current script) then runs some cleanup code (sort of like the "finally" block of code in java).
But how to Control-C programatically?

Joel,

This thread http://www.mathworks.com/matlabcentral/newsreader/view_thread/246447#634250 asks basically the same question, with the short answer being that it can't be done.
