Interesting. I'm having a similar issue: I'm using

[[manager.prepend_keymap]]
on = ["<Backspace>"]
run = 'shell "kitten run-shell kitty @ set-tab-title "Yazi terminal" ; kitty @ set-tab-title "Yazi"" --block --confirm'
desc = "Open shell here"

and when pressing <Backspace> for too long while in the input field, this keybinding is triggered and I'm brought into a shell.

This is annoying.

Why not use <C-u> if you want to clear the whole input?

It's a more convenient and direct way, so you don't have to keep hitting <Backspace>. If you're in normal mode, you can also just c => c

I'm aware of this binding but I'm just so used to <Backspace> for some reason. I'll try to adopt it I guess.

I'm not always decide to delete all content when I start to delete them. Usually when I have deleted half of the content, I realized the rest of them is wrong too, so I'll keep backspace to delete all of them.

I just got another report about this issue: #1681. It seems like enough people are bothered by this behavior, so I think we can just remove it since it's a breaking change anyway, and it's also hard to come up with a way (like warnings) to prompt users with the existing backspace --under config to replace it

What about change this option to --no-close to make it not break?

No, just remove it - if enough people are bothered by it, then its worth breaking.

I'll also keep this PR open for a while to see if there are any differing opinions
