<C-Backspace> to delete a word

[savchenko]

In regular fzf I do --bind 'ctrl-backspace:backward-kill-word' and it works just fine.

For some reason, all attempts to replicate this in fzf-lua fail. Why?

Probably neovim’s interpretation of ctrl-backspace, go to insert mode and press ctrl-v-u and then press ctrl-backspace - what does it enter?

I get ^H which means I would use ctrl-h fzf mapping to make it work in neovim.

Hmm... Strangely, no. However, from the same shell:

> echo $FZF_DEFAULT_OPTS 
--bind 'ctrl-backspace:backward-kill-word' # + other parameters

Have you tried adding the bind to keymap.fzf? What happens if you run :FzfLua files keyamp.fzf.ctrl-backapace=backward-kill-word?

[savchenko]

OK, so the recipe is:

• Remove the binding from keymap.builtin
• Do not touch vim.env.FZF_DEFAULT_OPTS in nvim.
• Add bind to fzf_opts:

  fzf_opts = {
      ["--bind"] = "ctrl-backspace:backward-kill-word",
  }

This particular combination works as expected. Why? No idea, but it works.

• Remove the binding from keymap.builtin

When you use keymap.builtin you’re overriding neovim’s teminal mapping :tmap … on the fzf main buffer so that would obviously override the fzf mapping.

Do not touch vim.env.FZF_DEFAULT_OPTS in nvim.

Unrelated IMHO, unless specifically overridden fzf-lua will inherit the settings from the shell env.

Add bind to fzf_opts:

IMHO it’s better to add the bind to keymap.fzf:

  keymap = {
    fzf = {
        ["ctrl-backspace"] = "backward-kill-word",
    }
  }

This particular combination works as expected. Why? No idea, but it works.

If you like your solution keep it, nothing wrong with it.
