Font size and line height
Default Font Size under Typography is the size of one body paragraph. The default is 12pt and the list runs from 8pt to 72pt, but you can also type a number straight into the field. Decimals like 13.5 are accepted, and pt is appended for you. Headings follow it by a multiple. With the body at 12pt, a level 1 heading is 24pt and level 2 is 18pt. Line height is Default Line Height under Spacing. Nine steps from 1.0 to 3.0, with 1.5 as the default. It leaves paragraphs you gave a line height of their own alone, and reaches only paragraphs and headings with no setting of their own.
Set the body size and heading sizes follow it by a multiple.
Word break
Word Break under Line Breaking decides how a line wraps at the right edge. Break by word does not split a word; it drops the whole word to the next line. Break by character breaks per character, keeping the right edge straight. The default is by word.Markdown, slash, and mentions
The three switches under Editing all start on. Markdown commands turns symbols at the head of a line —# and a space, - and a space, --- — into formatting. Turn it off to keep symbols as symbols. * * *, used for a scene break, does not become a list even with it on. / commands brings up the formatting and insert menu, and @ mentions links documents, sheets, folders, plotboards, and canvases from the same project into the body. Turn mentions off and the mentions already placed can still be clicked through.
The three input methods are turned off one by one.
