I am looking for a program for OS X that can prevent the user from inputting the same key twice in less than X milliseconds. The set of keys for which this limitation applies to should be configurable.
Any price and license is fine.
I found Unshaky on GitHub (https://github.com/aahung/Unshaky)
I've been testing it for about day and so far it has been working fabulously! During a full workday I experienced a double-keystroke only once.
Please note that you have to set it up:
I put 40ms delay for each key:
I also made an exception for the Tab and Delete keys which I regularly hit repeatedly:
I am not affiliated with Unshaky in any way.
