While keyboards differ according to manufacturer and model, the information here should apply to most laptops and desktop PCs. We'll also explain why Macs don't have a Num Lock key, but do offer some accessibility functionality via the numeric keypad.

What Does Num Lock Do
A number-lock key replaces the functions of certain keys on the keyboard with a numeric keypad. Some computers automatically turn on number lock during startup, but you'll have to enable the feature manually on most compact keyboards.

This often-ignored feature can be helpful in several situations. For example, some people find it easier to type long sequences of numbers using a keypad, such as those found on phones and calculators. Also, you'll need to activate Num Lock sometimes to type special characters like curly quotes.

The Num Lock key is usually located in the upper-left corner of the keypad. If you're using a laptop with a numeric keypad, the Num Lock key will be in the same place as a desktop keyboard.

Compact laptop keyboards, however, don't have a numeric keypad, so number-lock functionality usually shares a key with another key, such as the Scroll Lock key, near the Backspace key. If a key has two functions, the alternate function might be labeled in a different color.

If Num Lock is labeled the same color as the Fn key, then this is probably the case. Laptop keyboards vary and may have different configurations.
What About Macs
On Mac keyboards with a numeric keypad, the number keys function only as number keys, so there's no need for a separate number-lock function.

The Clear key is typically located where the Num Lock key would be on a PC keyboard. Although they don't technically support number lock, most Macs have a built-in accessibility feature called Mouse Keys that lets users control the cursor with the number pad.

Once enabled, the number lock key will remain active until you disable it. Num Lock works like the Caps Lock feature in that it can be toggled on and off by pressing the appropriate key.
