how2 add header in 3d window? (2.72) clicked "+" but get "tool" panel...

to start with, i really tried hard to find this on faq’s, googling, this site… but no dice. I’d think it’d be a common question.
…i apologize if it’s really obvious.

(is it true that “header”, “toolbar”, and “menu bar” all mean the same thing, at least sometimes? that’s a little confusing…)

ok, so i think my title says it all, but, for clarity, I’ll reiterate:
I’m trying to get a header to appear inside a 3dview window, and when I click on the 2 little plus signs, (see arrows in 1st screenshot), I get a “N” panel and a “T” panel, but no header.

I’ve attached a couple images
a “before & after” of me following the directions, as I understand them.



thanks in advance for y’all’s assistance!
