Set how quickly a key repeats on Mac
If you press and hold certain keyboard keys when in a text area, the key’s character begins to repeat. For example, the Delete key continues to remove text for as long as you hold it down.
You can set how long you must hold down the key before it starts repeating and how fast it repeats once it starts.
On your Mac, choose Apple menu
> System Settings, then click Keyboardin the sidebar. (You may need to scroll down.)
Drag the “Delay until repeat” slider on the right to set how long to wait before the character begins repeating.
Drag the “Key repeat rate” slider on the right to set how fast characters repeat.
You can add accent marks and special characters to some letters. For example, click and hold the a key to type à, á, â, or other characters.
If you set the “Key repeat rate” slider to Off, special characters won’t appear when you hold down a key.
