[orca-list] What makes alt+super+s work?

[John G Heim <jheim math wisc edu>]

I recently installed debian on a laptop "by hand". I mean, I typed in 
the commands to format the hard drive, ran debootstrap, wrote an 
/etc/fstab file -- the whole works. Everything is fine except that 
alt+super+s does not appear to work. I can start orca by hitting alt+f2 
and typing "orca". But it doesn't start if I press alt+super+s. I am 
guessing I need to install some package where that is configured.
