Feature Request: Select Vomnibar Result without Arrow Keys

First off, this extension has been life changing. Thank you to the community for building and maintaining this work of beauty.

When I'm using the vomnibar after typing my query I'm using arrow keys to get to the result (please let me know if there is a better way already!). It feels way more vimmy to be able to use a command to select something arbitrary in the list based on index. Why press a key six times when you can add six to something else?

Alfred has a nice approach to this. Enter selects the first result. Cmd-N selects the N+1th. The icons on the side make it super easy to "discovery" this. Maybe something similar would work for vimium?

Start at the Vomnibar's existing result-selection and keyboard handling; the issue does not name a file or test. Compare the current arrow-key behavior with indexed shortcuts such as Cmd-N, including the requested visual discovery of indexes. Done means an arbitrary result can be selected without repeated arrow presses and the behavior is covered by appropriate tests.
