Another step in making hildon-desktop keyboard friendly:

Now keys work in the application menu (launcher) and window switcher:
q - selects the top left thumbnail/icon
w - selects the top, second from left
...
a - selects the left of the second row

And so on. In addition, in the window switcher pressing shift or FN together with the letter closes the window instead of moving to it.
