That still doesn't seem to work. The code I put this in (before a
halt) never halted, though I sat on the shift key. When I test in a
(Delay forSeconds: 1) wait. ActiveEvent anyModifierKeyPressed
is always true, but shiftPressed is always false. One possible
explanation is that the relevant event is the one causing the
evaluation (alt-p). But at any rate I still can't get a hold of the
current keyboard state.
