Alt Key Codes List for Windows : Type Special Symbols using Keyboard

This should work in any Windows word processor, text editor, browser or email client.
Make sure your keyboard is in NumLock mode.
Hold down the ALT key and enter the number on the numeric keypad. (Note that many laptops have a blue FN key that changes a set of keys, also with blue numbers on them and usually in the 7-8-9-U-I-O area, into a numeric keypad.)
