Should the prefix `C-x 5` take keys from the `C-x` keymap?
So any key in the `C-x` keymap will be automatically
available in a key sequence starting with `C-x 5`?

For example, `C-x C-d` is bound to `list-directory`,
then the inferred `C-x 5 C-d` will show the output
of `list-directory` in a new frame?
