[Suggestion]: Add functionality to clear the nvim picker input

[GunawanAhmad]

Which fff frontend(s)?

Neovim plugin (fff.nvim)

What problem are you trying to solve?

I usually use <C-u> to clear the current input, so I keep reaching for it in the picker.

Right now the Neovim picker does not have a way to clear the input query. I know <C-u> is currently mapped to preview_scroll_up by default, but that can already be remapped.
What I need is a function for clearing the query, so I can move preview scrolling with another key and use <C-u> for clearing input.

For example:

keymaps = {
  clear_query = '<C-u>',
  preview_scroll_up = '<C-b>',
  preview_scroll_down = '<C-b>',
}

Proposed solution

Add a new clear_query action to the picker keymaps.

For example:

keymaps = {
clear_query = '<C-u>',
preview_scroll_up = '<C-b>',
preview_scroll_down = '<C-b>',
}

clear_query would clear the current picker input, keep the picker open, and keep focus in the prompt so the user can immediately type a new query.

Maybe the default for clear_query can be unset.

This would let users remap preview scrolling away from <C-u> while keeping the current default behavior unchanged for existing users.

Hi @GunawanAhmad , you can utilize the "cycle_forward_query" function to clear the current input. ]

    keymaps = {
     # other keymaps
      cycle_forward_query = { "<C-u>" },
     # other keymaps
    },

I think we should add a standard set of keymaps to clear the line in neovim.

I personally use C-w exclusively but it make sense

A clear-input action would fit well as a configurable keybinding rather than only hardcoding <C-u>. Some terminals/editors already use Ctrl+U semantics for line clearing, while users may want different mappings in the Neovim frontend. A tiny test that the picker query is cleared without changing the selected item would cover the behavior cleanly.
