ctrl-L (C-l for short)  is old standard terminal key-binding, sending an
actual control-character. Control-characters are like their regular
counterparts but with a numeric value 0x40 less. Others that you
probably know are C-c (0x03, break) , C-d, C-/ . More obscure are C-s
(aka XOFF) to suspend terminal output, and C-q (aka XON) to continue
output. All these are control-characters used forever on unix terminals.

Also fairly standard C-h (backspace) C-p (previous) C-n (next). C-j is
synonym for carriage return aka \r, C-m is line-feed aka \n. Good to
know when keyboard mappings get screwed up.

In this context C-l is actually sending page-break control-character,
which will usually redraw the terminal window, unless the app decides to
use it for something else.

These control-codes can be seen in an acii table, they are the first ten
code-points.
