The Problem
Mechanical keyboards sometimes have a problem known as "chatter", wherein certain keys will seem to repeat keystrokes two or more times very rapidly when only pressed once.
The Existing Solutions
So solution number one is obvious: just replace the broken key switch (or the entire keyboard).
Solution number two is: Well, there are existing software solutions, that block very rapidly repeated keystrokes to fix the chatter problem. I've been using "Keyboard Chattering Fix v 0.0.1", Copyright in 2014 to the "Keyboard Chattering Fix Project"... I can't find an appropriate source link for this project, likely it was just a one-off creation in 2014 without updates and there's not much more to it. I've also come across "Keyboard Unchatter" by ZoserLock here on GitHub at ZoserLock/keyboard-unchatter (opens in a new tab).
The Limitations of The Existing Solutions
Replacing keyboard switches or entire keyboards, of course, can be difficult to do and tends to cost money. A software solution may be preferrable to many people.
Both of the mentioned software projects projects seem quite... decent, but they lack some critical functionality. In my case, the "h" key has a chatter problem (when I type "the", it types "theh"). The chatter is in the 100ms range... and I really don't want to block all keystrokes under 100ms (I'm a fast typer). Unfortunately, these existing options don't have a solution for me... so, instead, I've made a solution that fits my case and present it here to the public. (Also, with all due respect to the authors of the mentioned projects: I can't find source code to one, and the source code for the other isn't particularly clean or well written.)
This Project's Solution
I've taken a similar approach to the software…
