@Burey's answer is best. If you want to see a code where this precise thing is working:

Just look at the two <button> tags (ignore the rest, even if it throws an error; the buttons still work).

The 'slow down' button disables itself when clicked, then it enables the 'stutter' button. You can see them go black/grey when enabled/disabled.
