Remove custom keystroke translation

Fixes #89

I just checked this PR independently with the example you have provided in #89

But this does not open the popup for me at all. Did you test this with the change of another of your PRs together to get it to work?

BTW thanks for all the contributions ❤️ and sorry that it takes so long for me to review them, as I am currently a little occupied by work 🙈

Hey, don't worry about it! I am currently on vacation, usually I am also not always that keen to continue programming after doing that for the day job :)

Yes, I originally tested this as part of #90 but didn't want to do too many changes together.

I guess the main thing to test here is that it does not break existing stuff and then we can check after merging this if the descriptions work in the other PR.
I tested \\ handling for example because I removed the custom bit for that.
And my <leader> bindings also still work.
