Gtk+ 3.0 Hit-a-Hint

Mouseless keyboard navigation.

# apt-get install gcc make valac libgtk-3-dev libatk1.0-dev libatspi2.0-dev
$ git clone https://github.com/lethalman/gtkhah.git
$ cd gtkhah
$ make
$ GTK_MODULES=$(pwd)/gtkhah.so gedit

Now press Ctrl+Alt+E to start hinting. Press ESC to stop hinting.

Hitting keys may seem a little unresponsive due to listening to key release events rather than key press events.
