Sigh. I have no idea what I changed, but I can’t make outline-type lists anymore. Before, when I started making a list, if I were to hit TAB after one of the numbers, that element would go to the next level of the outline; shift tab moved it back. Now both just put a stupid tab in there. Please help me fix this before I snap and kill Bill Gates. Thank you.
Check in Tools > Options > Edit that “Tabs and backspace set left indent” is still checked.
You may also have previously been in Outline view, and are now in Normal, or some other, view. Check the View menu.
