Does anyone else accidentally use invalid keyboard shortcuts when doing something on a friend's computer? I use Emacs so everything is weird XD

Ok so I just changed my keyboard layout to neo2 because qwertz can suck my balls. Looking quite good so far. I've been writing some smaller texts and it looks like you can get used to it quite fast (i also changed because I wanted to learn writing with 10 fingers anyways. Not that I've been writing slowly before, but why not).

The bad thing: all shortcuts (vim etc) feel strange because I have to betray my muscle memory now. So I thought I might also just switch to emacs now. Have to learn it from the beginning but it might be worth it.

Did anyone of you have any experience with neo (german) and what editors did you use?

After meet emacs, I NEED keyboard shortcuts even for visual interfaces and chill apps. Even, for apps like Telegram, WhatsApp, Magnet (Windows Manager for OS X), Photoshop & Illustrator among others.
