Directional arrows: Up, down, right, left. "inverted T" seems an unusual way to put it. (To me, anyway!) Is that a common tech term?

Sorry, Jim...that term really isn't popular these days. Didn't mean to confuse....

Good thing you didn't say "reverse Tau" like I've heard some geeks and 1337-wannabes call it.

O_o W,T..? I'm not even going to bother with the Greek bit as all things pedantic tend to involve that or Latin it seems ... But the reverse bit? That's just wrong. How do you tell if a (perfectly symmetrical) 'T' is reversed? Are there hooks, sticky pads, or clamps or something on the back? Inverted means to turn upside down...that makes sense. Reverse...not so much.
