I want to do things with the keyboard, but I have no Idea even where to begin. I hear people talinkg about thinks like "press SHIFT-TAB" - where is there a TAB buton on the N900?!

Please understand, I'm not talking about writing scripts to hack key locations. I'm talking about learning which keys are which, and which combinations to press to do simple things like switch between open windows, rotate the screen, etc.

Thanks for the beginner's advice.
