This was my point in my comment[0] in that thread. I've used GUI Emacs for years, it's way better than the TUI version and fully keyboard driven.

Interestingly, people have seen my GUI Emacs and commented "I didn't know you could get images in a terminal". Then I have to tell them it's not a terminal...

If I had to pick the absolute worst things about Teams, which is already one of the worst pieces of software ever made, it would be that it's not keyboard driven at all.
