I would like to hope so, I haven't tried intercepting something like that(I just listen for certain keys), I do wonder if someone more experienced than me could listen for Ctrl and alt, then intercept the delivery, and display their own. (I would 'assume' the system gets first dibs on any keypress, but what if you listened for Ctrl and alt then used a sendkey to upkey the Ctrl and alt, and detect a del key press and then display a fake).
