how can I revise text within a text box

since I can’t rotate a paragraph or frame 180 degrees, I cut & pasted text into a text box. short of re keying & re pasting everything, how can I make a correction to that text? of course the simple fix would be to allow the rotation of objects to other than 90 & 270 degrees. see also bug 100386 concerning text boxes. is their documentation of text boxes anywhere?
