Comment 6 for bug 891620

+1 to the circular mode. As for the starting point, I think we will have
to do some user testing.

Both have awkwardnesses (which is why we never mapped Alt-TAB into the
launcher). If you always start from the top, then it would be better to
use Super-<n>, which goes straight to your <n>'th launcher. If you start
from the current focus, then you need a mind which remembers the
launcher sequence perfectly :-)
