    I don’t use CoC and I don’t know every Lua API function so this might be clunky, but the following works on my machine:

    function _G.show_documentation()
  local ft = vim.bo.filetype
  local cword = vim.fn.expand('<cword>')
  if ft == 'help' or ft == 'vim' then
    vim.fn.execute('help ' .. cword)
  --[[ elseif vim.fn['coc#rpc#ready']() then
    vim.fn.call('CocActionAsync', {'doHover'}) ]]
  else
    vim.fn.execute(vim.o.keywordprg .. ' ' .. cword)
  end
end

vim.api.nvim_set_keymap('n', 'K', "<Cmd>call v:lua.show_documentation()<CR>", {noremap = true, silent = true})

    Note that I commented out the elseif statement since I don’t have CoC and the function fails if it can’t call coc#rpc#ready.

      Thank you! I’m gonna study this well before I copy paste time around.

      E: it works! Somehow the Lua version is easier to read and understand as well.

        Glad to hear it! Had to go digging though the help pages to find out what expand() did in the original and how to get the word under the cursor in Lua
