comando screen quick tips

screen is a much under utilised program, which provides the following functionality:

Remote terminal session management (detaching or sharing terminal sessions)
unlimited windows (unlike the hardcoded number of Linux virtual consoles)
scrollback buffer (not limited to video memory like Linux virtual consoles)
copy/paste between windows
notification of either activity or inactivity in a window
split terminal (horizontally and vertically) into multiple regions
locking other users out of terminal
