For the Bb-B (or A#-B) trill (in both registers), play Bb as normal, but with LH finger 1 hold down both the top fingerplate and the small spatula attached to the key just below it to stop it opening (and giving you a C instead!), and trill with LH finger 2. You'll probably have to reach across with your left index finger to hold this key down as well as the top fingerplate.
So it's x,xo|xoo for Bb, and x,oo|xoo for B.
This trill is a doddle on flute, clarinet and sax - but a pain on the oboe.
And holding this small key closed with the top fingerplate also stops the C key opening when playing in sharp keys, and intervals across the break involving B (eg. C#-B, D-B, D#-B, E-B, etc.) as it keeps the key closed so stopping the accidental 'blip' of the note C when RH finger 1 is closed.
Here's a pic of a cocobolo XL that should be like your teacher's:

If you look just to the left of the extension plate on the top fingerplate you can see the small spatula key - that's the one you need to hold down for the trill.
