Keyboard accessibility

[bertob]

The entire interface should be accessible using only the keyboard.

examples:

• It should be possible to choose a result from a suggestion list with the up/down keys and select it using enter.
• similarly, results from routing API should be navigable with the up/down keys and the details for a route should be shown when enter is pressed.
