Sortables without the mouse (i.e. via callbacks)

Sortables without the mouse (i.e. via callbacks)

I downloaded the full jQuery UI bundle and played around extensively with the demos.  One thing that interested me was Sortables, though all the demos only provide a mouse interface.

Is there a way to use Sortables via commands?  Like instead of clicking and dragging a sortable, you create an input button and when pressed it rearranges the stack?

Any brief example would be appreciated greatly.  I'll continue looking into it myself in the mean time.  Thanks in advance!
