Multiple applications can select events in the same X window at the same
time. For example, the classic debugging tool xev(1) selects events on
a window you select (say, an Emacs frame), and outputs a trace of those
events. Which is active: xev, or Emacs (which also receives those input
events and acts on them as if xev didn't exist)?
The only sane answer is "both of them".
