ASCII symbols

Special ASCII symbols can be generated in common versions of Windows applications by activating the keyboard NUM LOCK function, pressing the ALT key, and entering certain numbers in the numeric keypad (located on the right-hand end of the keyboard) while the ALT key is held down. The symbol appears when the ALT key is released, after the number has been entered.

The following table denotes the symbols available using this technique. These symbols are generally not found on keyboards, but they are viewable in most word processors and Web browsers.

An extended set of symbols is viewable in more advanced Web browsers. We are currently preparing a table of extended symbols available with Unicode.

hold ALT down, and
