Update DBC-2108A adds T as a new Point-and-Shoot command. This is most useful when placed on the targeting operand of any branching (or jumping) instruction. It sets a temporary breakpoint at the branch's target. So if you have several branch instructions in view, you can easily set traps at all of their targets with a single ENTER press, and without having to actually view those targets first.
One very good use case occurs when you have stepped into a loop, and you want to let the loop run to completion and recapture execution when the loop is completed or exited. This T shortcut lets you quickly and easily place traps at all of the loop's exit targets.
