The keyboard repeat-speed setting, from 0 (approximately 2.5 repetitions per second) through 31 (approximately 30 repetitions per second).
Remarks
This property indicates the time between each keystroke repeat message that is sent when a user presses and holds a key down. This is a value in the range from 0 (approximately 2.5 repetitions per second) through 31 (approximately 30 repetitions per second). The actual repeat rates are hardware-dependent and may vary from a linear scale by as much as 20%.
The keyboard_delay property indicates the length of time after a key is pressed and held down before keystroke repeat messages are sent by the operating system.
