If you use bash (or zsh, and maybe others), hit ^L (control-L) to clear the screen. From the bash(1) manual:

clear-screen (C-l) Clear the screen leaving the current line at the top of the screen. With an argument, refresh the current line without clearing the screen.

I must hit ctrl-l a thousand times a day, learned it before I knew of clear.
