keyboard navigation needed Rated 5 out of 5 stars

This addon is irreplaceable.
I think everyone (who uses keyboard) would love this addon if keyboard navigation worked:
That is: to switch matching tabs by means of the keyboard arrow keys. Then press ESC to close the menu.

As it is now, the addon is buggy.
The Down arrow key does not switch to the first matching tab (like the location bar would do with a bookmark or history entry). But the Up arrow key seems to work fine (it switches to the last matching tab), the first time.
Once you have switched to a tab, the menu loses focus and it is not possible to press arrow keys to switch to the following tabs (like scrolling does).
Also, the Esc key clears the text, which is useful, but it makes more sense that the Esc key closes the menu (and it is more useful, as there is no other way to close the menu by means of the keyboard)

This review is for a previous version of the add-on (2.4.1-signed).
