See also byobu, which is one step better than screen.

Taking Screenshots in Mac OS X

Shortcuts

* Command-Shift-3: Take a screenshot of the screen, and save it as a file on the desktop
* Command-Shift-4, then select an area: Take a screenshot of an area and save it as a file on the desktop
* Command-Shift-4, then space, then click a window: Take a screenshot of a window and save it as a file on the desktop

* Command-Control-Shift-4, then select an area: Take a screenshot of an area and save it to the clipboard
* Command-Control-Shift-4, then space, then click a window: Take a screenshot of a window and save it to the clipboard

In Leopard, the following keys can be held down while selecting an area (via Command-Shift-4 or Command-Control-Shift-4):

* Space, to lock the size of the selected region and instead move it when the mouse moves
* Shift, to resize only one edge of the selected region

GNU screen

Type 'screen' after you log into a server.

Or type byobu for an enhancement to GNU screen!

"Allows users to quickly switch their .screenrc to any of the available profiles"
See also http://launchpad.net/byobu
byobu version 3.5
Screen version 4.00.03jw4 (FAU) 2-May-06

Byobu features:

• Visible at bottom of screen at all times:
• All screen tabs
• Server welcome message
• Uptime
• Load
• Hardware spec
• [configurable to display anything you want]
• Tab names show special characters to provide more info:
• - (dash) means that window will be switched to with Ctrl-A, A
• @ (at) means that tab has seen activity since you last saw it

Screen keyboard commands:

• Ctrl-A, c -- to create a new terminal session
• Ctrl-A, Ctrl-A -- to alt-tab
• Ctrl-A, " -- to list the terminals
• Ctrl-A, A -- to rename the terminal
• Ctrl-A M -- (monitor for activity) Toggles monitoring of the current window
• Ctrl-A _ -- (monitor for silence) Toggle

Best screen feature:

1. Log into the server.
2. Type screen to start a session.
3. Work as normal.
4. When finished, just close/kill the terminal program, don't log off.
5. Later, on any (other) PC, log into the server again.
6. Type screen -D -R to retrieve your session, just as you left it.

I don't know of a way to change the order of the tabs.
