Using the keyboard for Launcher interaction is limited

When you press Super and the icons get the 1-9,0 overlay they only over the first 10 items.
If there are more icon they simply get pushed down and can't be access via the keyboard shortcuts.

One possible fix would be to use the first/last shortcut to scroll the Launcher icon list.

So if we have

Firefox 1
Tomboy 2
Banshee 3
...
Gedit 0 - then zero here could be an arrow instead of the Gedit icon that would scroll the list in big steps. Pressing 0 in this case would move the list by 9 places down (or until we hit the end of the list).
