Coauthors have been linked properly via GitHub Desktop built-in function to do this work hopefully

[autofix-ci]

Autofix has formatted code style violation in this PR.

I edit commits locally (e.g: git, github desktop) and want to keep autofix

1. Run git pull. this will merge the automated commit into your local copy of the PR branch.
2. Continue working.

I do not want the automated commit

1. Format your code locally, then commit it.
2. Run git push --force to force push your branch. This will overwrite the automated commit on remote with your local one.
3. Continue working.

If you don't do this, your following commits will be based on the old commit, and cause MERGE CONFLICT.

Okay so evidently #4636 contained the file changes for this PR and the other one so these can be closed? According to Kenan at least.

I'm going to hope this is the right decision, if anyone spots anything vital in this re-open and fix merge conflicts then, bleh.

[chaosvolt]

Okay so it turns out merging that other PR was a mistake for reasons entirely unrelated to splitting them weirdly and instead just because the source PRs in #4635 specifically need more time in the oven before we want to port them, so I think this one specifically is 100% good to reopen after the revert, then we need to go on to figure out if anything in #4635 can be separated from the bad keybind code changes and salvaged, then lastly grab anything unique to #4635 as its own PR.

[chaosvolt]

Compiled and load-tested, seems good at first glance. More importantly, no keybind errors so I can confirm that nothing critical from #4635 snuck into this one.

That said I'd like to leave this for Coolthulhu, Scarf, or Kheir to look at and make sure they give it their approval before any merges.

This should be redundant due to #4713

Closing this because pull request of @KheirFerrum includes fixed version of this work
