I feel dumb for asking, but I've wasted so much time already on this: I just want to summarize some things so it's easier for me to study. To structure my document, I'd like to use different levels of headings. level1 headings should have the biggest font size and a different color from level2 headings; same goes with respect to level3 headings.
I formatted some stuff under "Styles" (see picture). Now I want that when my level1 heading is "2.", my level2 heading is "2.x". Instead, as you can see, it's "1.x".
Less importantly: under References < Add Text you can assign the level of text for the table of contents. Can I assign this automatically to my user-defined styles (so level1 heading is automatically "Level 1", level2 heading is "Level 2" and so on)?
