Explorer doesn't toggle with a specific keymap

[ajinkya-k]

Hello! I had configured <leader>fe to toggle the snacks explorer. it works as expected, it opens the explorer on the side if its closed, and closes it if its open. However, I am trying to remap it to ctrl-b but when using this keyboard shortcut the explorer doesnt close if its already open. The only thing I changed is the key combination. can someone help?

You're focused on the Explorer when the key is triggered, so its buffer keymap take precedence over your global keymap. I wouldn't recommend using <C-b> in this case; instead, consider using <leader>b or something similar. However, it's also easy to override buffer keymaps:

vim.keymap.set('n', '<C-b>', function() Snacks.explorer() end, {})

opts = {
  picker = {
    sources = {
      explorer = {
        win = {
          list = {
            keys = {
              ['<C-b>'] = 'close',

Thanks! So I am fairly new to nvim and the config that i borrowed from had mapped to nvim-tree-toggle, so I thought it would be harmless to remap it to toggle with snacks explorer

:verbose map <c-b> (or any other mapping that you want to check for) is your friend (you can also use nmap explicity for normal mode or imap explicitly for insert mode and so on). It will show you that it's bound to preview_scroll_up and that comes not directly from the Explorer keys themselves, but from the default keys

that every picker inherits.

Subsequently every picker's explicit keys overwrite the default ones, if there's a conflict.

Thanks for the detailed explanation. I switched it to command B instead of ctrl B
