Great! Very useful responses; thanks!

I guess my complaint (maybe fixed in the n900?) is that the toolbar setup doesn't make it clear what maps to what (here, "bar" -> |) Is there a guide out there somewhere that I've been missing all my life? I tried to add the literal character and (I think) the word "pipe." It silently accepted my input. However, whenever I hit the "button," it just stared at me blankly.

Just goes to show you that it doesn't pay to spend your time graduating; you lose sync with what's important in life.
