Typematic Rate Setting
This determines if the typematic rate is to be used. When disabled,
continually holding down a key on your keyboard will generate only
one instance. In other words, the BIOS will only report that the key is
down. When the typematic rate is enabled, the BIOS will report as
before, but it will then wait a moment, and, if the key is still down, it will
begin the report that the key has been depressed repeatedly.
For example, you would use such a feature to accelerate cursor move-
ments with the arrow keys.
