I haven't really consciously tried to teach Oz any hand signals,
but he's learned them based on using a treat to guide him into
the position I want him. So he'll now do the following with a
hand signal: Sit, Down, Stay, Shake, Take It and Come.

For bringing me something I've started naming his toys, so
I'll say "Bring me your Ball" or "Bring me your Hedgie". I'd like to
eventually expand out on this to other household items. Is
anybody using hand signals to go pick up an array of different
items, no matter what room they're in (so you wouldn't be able
to just point at them) and bring them back.
If so, are you using like sign language for the deaf to do it?
