It would be good to be able to switch tasks (on open task switcher) also with the arrow keys (up and down). This is already implemented on "Flip switcher" or "Cover switcher". It would allow easier work with two hands on a keyboard, also very comfortable reverse rolling tasks when you have a lots of tasks in the switcher (If you miss a task, you need to go through the whole list with Alt-Tab).
Maybe it would be fine to switch tasks also with the mouse scroll wheel.

Reproducible: Always

Steps to Reproduce:
1. Set Informative task switcher on in the System Settings
2. Open few windows
3. Push Alt-Tab to launch the task switcher


Actual Results:  
You don't have the opportunity to switch tasks with arrow keys.

Expected Results:  
On open task switcher to push Down arrow key and to go on the next task. If I'm on the first task, when I push Up arrow key I expect to go on the last task.
