SCROT is a simple command-line utility for taking screenshots. The simplest way to utilize SCROT is by hitting the "Print Screen" button on the keyboard. An image of the entire screen will appear in the home folder. Many commands may be issued in LXTerminal to control SCROT including image format, time-delay, a particular part of the screen, etc. For many of SCROT's useful commands, just type: man scrot in LXTerminal. For tips and tricks see Gary Richmond's "How to take screenshots" in Free Software Magazine.
