@b0rk One trick I like is to make it super easy to lookup man pages. I run my shells inside Emacs and I setup a keybinding that pops up in another window the man page for the command at the cursor —so I can keep typing the command while looking at the man page. I bet it would be easy to do the same in, say, Vim or even screen or tmux, with the man page showing up in a split.
