Trigger action X from thing Y.
For example, bind the F11 key to action -t f11 (-t for trigger) in your favorite window manager and
run (-b for bind):
while action -b f11; do screenshot; done
in your favorite terminal emulator when you're working with something you want to screenshot.
Note that the f11 string is arbitrary, i.e. go crazy, what about volume_up, fix_wifi, call_mom?
