How to scroll up and look at data in GNU screen
Solution 1:
There's a 'copy mode' in screen, activated by pressing, Ctrl + A, followed by [. This gives you a cursor that you can use to scroll backwards.
Solution 2:
Add the following to your ~/.screenrc
:
termcapinfo xterm ti@:te@
termcapinfo xterm-color ti@:te@
This will let you use the Terminal.app scrollbar instead of relying on screen's scrollback buffer.
Solution 3:
The correct way is to use the copy mode, as Babu pointed out.
You could speed things up a bit by automatically entering into copy mode when you press your favourite scroll keys.
For example, using PgUp and PgDown:
# easier scroll
bindkey "^[[5~" eval 'copy' 'stuff ^b' # PgUp | Enter copy/scrollback mode and page up
bindkey "^[[6~" eval 'copy' 'stuff ^f' # PgDown | Enter copy/scrollback mode and page down
