Add:
- [:options](https://neovim.io/doc/user/options.html#%3Aoptions) to open
default settings
- :map to open default vim keymap

These aren't exactly the same as vim but i think it's a good equivalent

For map:
I can't find the docs for :map with no arguments, since the map docs
only shows the command bindings, but it opens the key mapping in vim.
