I’m guessing it has something to do with Calva-fmt/CLOJURE-LSP trying to do something on those keys.

but I have no idea how to track down what is going on

Yeah, and it’s only in my clojure buffers. No issues in any other file type.

Are you trying to delete delimiters like parens or brackets?

might want to look for commonalities to when those keys don't have the desired effect... for example, some editors with just the right paredit settings will prevent deleting parens that would make them unbalanced

not just parens

anywhere in the file

How did you get to the file? Did you navigate to source? Perhaps it’s a read only buffer

no, I can highlight text and type over it, which is how I am getting around not being able to delete

There are more people running into this: https://github.com/BetterThanTomorrow/calva/issues/2299 We haven’t been able to track it down yet. See if bypassing the structural editor helps, @U03D6G7KGUB. By pressing alt+backspace instead of backspace when you are experiencing that bug. If it does, then that is a clue.

Shift + backspace works.

At least for macOS

Yeah, it does the same thing as alt+backspace, so should also test the same thing.

alt+backspace removes whole line for me :D but anyway I’m happy shift+backspace works

I’m happy for that too! 😃

Unfortunately sometimes structural editing still hangs the whole editor
