To use this script, you need to have Tampermonkey or a similar user script manager installed in your browser. Once installed, simply copy and paste the code into a new user script and save it. The script should automatically run on YouTube pages and disable the spacebar scrolling behavior.

Note that this script may not work if YouTube changes its code in the future. If that happens, you may need to update the script accordingly..

just click the raw button on here with tampermonkey installed and it should have a tampermonkey popup with an install button

doesn't seem to work anymore after alt tabbing away and back in

Hey @alexwh I face the same problem, it doesn't work after alt tab and come back to youtube. Did you manage to solve this problem?

Is there a script that would add 'Copy Code' button to Github?

This should resolve the Alt-Tab issue.
