intuitive-ish

I prefer a 3 screen layout when at a desk with my Mac, but couldn't figure out what determined which screen got the Dock - sometimes it would jump for no apparent reason, and other times I wish I could make it go to another screen because it was interfering with a full screen display.

Turns out it's dead simple: pushing the mouse to the bottom of the screen (and a little beyond, I guess) puts the Dock on that screen. I think there's a good chance that having learned it I will remember it - so something can have that "semi-intuitive" flavor but discoverability can still be weak.

(I guess I should say I also like to have the Dock visible and not auto-hiding (I suspect auto-hiding may be the source of "move cursor to where you expect the Dock to be to make it show up there.) I suppose I like being able to see which Dock icon I'm aiming for as the pointer moves there, rather than waiting til the Dock shows up...)
