+then released. This depressed time is a different length for everyone. Auto Shift
 defines a constant `AUTO_SHIFT_TIMEOUT` which is typically set to twice your
 normal pressed state time. When you press a key, a timer starts and then stops
 when you release the key. If the time depressed is greater than or equal to the
-`AUTO_SHIFT_TIMEOUT` then a shifted version of the key is emitted. If the time

 is less than the `AUTO_SHIFT_TIMEOUT` time, then the normal state is emitted.
