Use the keyboard instead of the mouse to control your Mac.

Click Options to customize Mouse Keys:

Press the Option key five times to toggle Mouse Keys: Use your keyboard to turn Mouse Keys on and off.

Ignore built-in trackpad when Mouse Keys is on: Disable the trackpad on your Mac when you use Mouse Keys.

Initial Delay: Set how quickly the pointer starts moving when you press a key.

Maximum Speed: Set the maximum speed at which the pointer moves.

Ignore built-in trackpad when mouse or wireless trackpad is present
