When Caps Lock is on, all alphabetic characters typed are in uppercase.
When Num Lock is on, the separate keypad is in numeric mode. The keys
function as a calculator (complete with the arithmetic operators +, -, *, and
/). Use this mode when you need to do a lot of numeric data entry.
When Scroll Lock is on, the screen moves one line up or down when you
press the up or down arrow keys respectively. Scroll Lock does not work
with some applications.
