In many situations, you may require to type/insert special characters/symbols into your word documents to express the matter in symbolic representation. However, there are only a few symbols or special characters displayed on our computer keyboards. But, using special alt key codes, we can print various symbols like heart, trademark etc.
This should work in any Windows word processor, text editor, browser or email client.
Points to Remember
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.)
