I used to be a NeXTie, and the Screensaver.app there had a really nifty
little feature. I'm surprised it's not been copied into other screensaver
applications since, as it's pretty simple. They just had a facility where
moving the mouse cursor to one corner of the screen and leaving it still
for a few seconds would cause the screen saver / screen lock to come on
straight away.
Conversely you could designate another corner of the screen as "don't turn
on screensaver even after an extended period of idleness". Being a NeXT app
this was all configurable by dragging little '+' or '-' icons around a
scaled down image of the screen, or off it entirely if you didn't want that
facility.
Cheers,
Matthew
