In PC keyboards, the availability of symbols and special characters is very minimal. When you count the special characters, close to 20 characters will be available on a standard keyboard. But, there are hundreds of special characters and symbols hidden in the PC keyboard. You can insert those hidden characters by using the Keyboard symbol shortcuts.
Using the Alt codes, you can get more than hundreds of special characters on your PC keyboard. When using Alt codes, you need to press and hold the Alt key. Ensure you press the correct num key combination.
For instance: The Alt code, Alt + 0153, gives the Trademark symbol. You need to press and hold the Alt key, press the keys 0,1,5,3, and release the Alt key. The trademark symbol will appear.
