I use screen a lot for work. but when i want to see the history in terminal, typing ^a-[ and then up/down arrow gets tedious in a heartbeat. i discovered recently that you can put the following command in the ~/.screenrc file in the machine where screen is run, and you’ll have the capability to scroll through the history.

# Make xterm scrolling work properly with screen
