4.12.8 Refresh

Syntax: Refresh
Abbreviation: REF

refreshes the display. Refresh is very important, and should preferably be bound to the Control-L sequence, for historical reasons. It can always happen that a noisy phone line or a quirk in the terminal corrupts the display. This command restores it from scratch.

Refresh has the side effect of checking to see if your window size has changed, and will modify the display to take that into account.
