Editing Alt key (section)

===Windows===
In [[Microsoft Windows]], holding down the Alt key while typing in numbers (often referred to as [[Alt code]]s) on the [[NumPad|numeric keypad]] allows the user to type special characters not normally available on the keyboard. For example, holding down Alt while typing 0225 ({{key press|Alt|0}}{{key press|2}}{{key press|2}}{{key press|5}}) on the numeric keypad will result in {{char|á}}, the character at 225 in the (Western Latin) [[code page 1252]]. These extended keyboard characters are useful for persons using foreign languages, mathematics, currency symbols, business use, etc. Some computers work the same if the [[Num Lock key]] is on.
