Although I don't like to use the mouse if the keyboard will do just as well
(since it can easily break your train of thought) one of the things I do
use it for frequently is flipping between screens, and dragging them up
and down. However, just about every programmer starts his window up against
the top border - you may have to re-size then move several different windows
on several different screens before *all* the screen drag bars and *all* the
screen depth-arrangers are free.

Just say "expose" and it will do all this for you. Windows up against the
top border are sent a message saying "move down a pixel". If they happen to
be already as high as the screen, they are first sent a message saying
"get a bit smaller".

Note: I have not found anything that objects to this, although I'm sure that
      there are such programs. Be careful using it if you aren't familiar
      with the characteristics of the windows currently open. It's conceivable
      that a screen-size, non-resizable window could crash the system when
      moved (the Workbench backdrop window does not crash).

I did get some weird effects while experimenting. If I used Forbid() and 
Permit() it would work *once*, then not again until a re-boot. Instead a 
Delay() is used for 1/3 second every time it sends an IntuiMessage so that 
Intuition gets a chance to hear about it. There was also the Guru which showed 
up in two places, the usual black and red on top, and inverted Workbench 
colours down below, shifted to the left with wraparound. And the disabled
machine you get when you set IntuitionBase->FirstScreen to NULL (just to see
what would happen), although you can still move the mouse around you can't
"touch" anything.
