There are three funy little buttons in the top right corner of the keyboard.
PrtScn or Print Screen - this produced exactly what you see on the screen.
Technical people like to see this if you have a problem. SysRq this stands
for system requirements, but I don't know what it does.
ScrLk - Scroll Lock - this is to do with the cursor arrows, but I have
only ever seen it in Excel.
Pause/Break - this was from the olden days when things would take forever
to load, so that you could break it and try again.
