@genehack yeah, I could tolerate shell-like tab completion, where it's obvious I'm intending to get an unambiguous completion and a double-tab pops a completions menu. Zed, which is what I'm currently trying to use, defaults to tab instantly completing, and I suppose it must be possible to undo it with backspace or something, but it's super disorienting. I feel a lot of anxiety over stuff like that, it's like, "No that's wrong, what are you doing!? Stop doing wrong things, you're ruining it!"
