Apple hardware always stands apart from its PC counterparts. Keyboards have different keys, mice have only one button. While this is true, if you know where to look or what to do, you can replicate the functions from PC hardware on your Mac. Take the "Num Lock" key on the keyboard. This key lets you switch between numbers and characters on the keyboard's keypad. There is no "Num Lock" key on the Mac keyboard, yet you are not forced to only type numbers.
Open a word processing application.
Position the cursor where you want the character.
Press the "Clear" button.
Type the appropriate character.
Press the "Clear" button to return the keypad to numbers.
