What is the "T" setting commonly used for and how does it differ from Bulb ("B")?
With "T" you trip the shutter twice with the cable release. The first trip opens the shutter, the second trip closes the shutter. With a "B" setting, you open the shutter by pressing the cable release, and holding it in that position. Releasing the plunger closes the shutter. If your using "B", it is nice to use a cable release with a lock which keeps the plunger in the down position without having to hold it.
If it helps you to recall, B is for "bulb" (like the airhose squeezebulb shutters once used) and T is for "time."
