^L to refresh the screen.

In case of corruption. An obvious case of corruption is extraneous
output to the same tty (from an unrelated background process, or from
a rogue dbg! in this program itself). Another one I've been seeing
recently is a mysterious corruption relating to some Unicode
characters that only shows up in tmux on one system. But regardless, I
want to get on with my session after anything like that happens.
