Feature request: keyboard shortcuts

[ovk]

It would be really nice to have some keyboard shortcuts so that this extension can be used without a mouse (or clicking Tab multiple times).

One example is having some "quick access" key combination, for example Ctrl+N or just N (where N is a number), such that it will open corresponding bookmark.

Having basic support for vi-like keys would also be very helpful (hjkl for left/down/up/right, g - top, G - bottom, / - search).

Here's an example of some start page with shortcuts: https://github.com/kishlaya/Tiles#keyboard-shortcuts

Thanks!
I love keyboard and did my best to make the extension usable without the mouse 😃
This will be a great addition.
