Custom keymaps

Some plugin modules provide keymap options for your convenience. These can be disabled using {option}vim.vendoredKeymaps. It is also possible to disable individual keymaps with options by setting them to null. If a keymap is not provided by a module, you may easily register your own custom keymaps via {option}vim.keymaps.

{
  config.vim.keymaps = [
    {
      key = "<leader>m";
      mode = "n";
      silent = true;
      action = ":make<CR>";
    }
    {
      key = "<leader>l";
      mode = ["n" "x"];
      silent = true;
      action = "<cmd>cnext<CR>";
    }
    {
      key = "<leader>k";
      mode = ["n" "x"];

      # While `lua` is `true`, `action` is expected to be
      # a valid Lua expression.
      lua = true;
      action = ''
        function()
          require('foo').do_thing()
          print('did thing')
        end
      '';
    }
  ];
