BTW at the time I was using a Canon T70 and the users manual mentions Tv mode, along with Program mode, Manual, etc.

Very interesting. Tv is "time value" and Av is "aperture value." I know that all my Pentax, my old Olympus stuff from way back when, and all my Canon equipment used (uses) these notations. Of course, Nikon substituting "micro" for "macro", their own notation for modes shouldn't have surprised me!
