* Repeat Delay: This is the length of time that a key must be held down before the typematic feature is activated. Each time you release a key and press a new one, the delay "countdown" is reset. The larger the value, the longer each key must be held down before key repetition begins. If it is set too small, you may get keys repeating when you don't want them to. * Repeat Rate: This sets the frequency with which characters will be sent once the typematic feature is activated.
