12.5 History

— Command: history

(C-a {)
Usually users work with a shell that allows easy access to previous commands. For example, csh has the command !! to repeat the last command executed. screen provides a primitive way of recalling “the command that started ...”: You just type the first letter of that command, then hit C-a { and screen tries to find a previous line that matches with the prompt character to the left of the cursor. This line is pasted into this window's input queue. Thus you have a crude command history (made up by the visible window and its scrollback buffer).
