This is the new version of RunJavaScriptOnKeyPress, if you want the original version go here
It is a web based generator (I have tested it on Firefox, Edge, Chrome, Opera, and Brave)
You can use it here
I haven't had the time to fix it yet (haven't gotten back to it yet)
When I made the original version I was messing around with triggering JS on keypress a lot and got tired of having to look up the key IDs every time. I remade it because I remember having a lot of fun programming the original and it was well... kinda bad so I decided why not fix it?
