How to scroll skill bar with keyboard?

[kotyhoroh]

Hi!
I somehow accidentially scrolled skillbar with keys so now I don't see my 1 2 3 keys and attacked skills.
But can't scroll it back. I don't have mouse only keys and touchpad.
Don't see any key matching description in assigned keys.

Please help! )))

This is first thing I tried this doesn't work.
I see only asc1 key.

I took trackball from the drawer and fixed this but still interested.
