If you are used to using a standard keyboard on a PC, you have probably seen the Number Lock button in the top, left corner of the number pad. This button either allows you to use the number pad as numbers or disables the numbers and allows you to use the keys as arrows. The standard Macintosh keyboard does not have a Number Lock key, nor does it have arrows on the Number Lock number pad. Mac does have a feature, however, that will lock the number pad and allow you to control the mouse arrow as if you were using arrows on the number pad.

Step 4
