How do I operate the Succ-U-Bus?

Hint 1 of 5:

Read your manual.  It pretty much tells you everything that you need to know
about how to send something with the Succ-U-Bus.  You will need to know how
to use many of the features of your PET to get the Succ-U-Bus working.

Hint 2 of 5:

The key thing is to figure out how to give the proper destination to the
Succ-U-Bus.

Hint 3 of 5:

Use the designer room chevrons.  (One of the PET modes is just for those
codes.)

Hint 4 of 5:

When you're in a room, you can drag the code on your left into an empty slot.
 It will then be saved in your "inventory" of codes.  Do this while you're in
the room to which you want to send the item.

Hint 5 of 5:

After you've put an item in the Succ-U-Bus, drag the destination code the
Succ-U-Bus.  You should hear a sound to confirm the destination was accepted.
 Then, and only then, should you press the "Send" button.
