When typing in a Word document and using the tab key, Word indents entire
paragraphs, lines, and such. I don't want it to move any line other than the
one I tabed. I have gone to tools - auto correct - auto format and auto
correct and deselected every thing. It still auto moves things. This is the
most annoying feature of Word. Please tell me how to turn it off.
