screen: Copy Mode Keys
12.1.3 Markkeys
---------------
-- Command: markkeys string
(none)
This is a method of changing the keymap used for copy/history mode.
The string is made up of OLDCHAR=NEWCHAR pairs which are separated
by ':'. Example: The command 'markkeys h=^B:l=^F:$=^E' would set
some keys to be more familiar to 'emacs' users. If your terminal
sends characters, that cause you to abort copy mode, then this
command may help by binding these characters to do nothing. The
no-op character is '@' and is used like this: 'markkeys @=L=H' if
you do not want to use the 'H' or 'L' commands any longer. As
shown in this example, multiple keys can be assigned to one
function in a single statement.
