Question

Hi, I am trying to recreate the same behavior I got with folke/which-key of mapping Ctrl-r + Ctrl-w when I open a picker (Snacks.picker or Telescope). I want to be able to paste into the buffer whatever is under the cursor (which is the default behavior of n/vim in command mode). Which-key somehow configured this by default also in the picker input, but I can’t find any example configuration for clue.

Unfortunately, currently in 'mini.pick' there is no way to use <C-w> as the register after <C-r>. The best approximation is to manually populate w register after every picker start. Something like this:

local populate_registers = function()
  local win_id = MiniPick.get_picker_state().windows.target
  vim.api.nvim_win_call(win_id, function() vim.fn.setreg('w', vim.fn.expand('<cword>')) end)
end
vim.api.nvim_create_autocmd('User', { pattern = 'MiniPickStart', callback = populate_registers })

Then typing <C-r>w will insert "word under cursor" from the target window.

I think support of various <C-r><C-xxx> is an interesting idea to add to 'mini.pick'. I'll take a look.

@echasnovski is it something that should be handled by the picker?
I can have this behavior with which-key: https://asciinema.org/a/OiUm6C4xtFXxQ26eIJXqCh5zf

In 'mini.pick' case - yes. I already have prototype and plan to add it soon-ish.

I am not sure how/why 'which-key.nvim' affects the 'snacks.picker' in this way.

Most special registers are now supported out of the box. Thanks again for pointing out this feature!
