Yes, from within the X server. I've used Xlib in the past but this seemed
mostly limited to window management and keypresses when a specific terminal
in which a program is running has focus. I never came across a way to
simply monitor arbitray keypresses from a background program and take
action depending on them. For instance running a system command whenever
ctrl+alt+r is pressed.
