If a line of text is begun by typing one of the following marks...
* (asterisk)
- (n-dash)
-- (double-dash)
... (ellipses)
• (bullet point†)
...Final Draft will assume that a list is being created and when Enter is pressed at the end of the line, the next line will automatically start with that mark.
When the list is complete and the next line should begin without the mark(s), press Enter on the keyboard to delete the mark(s) and the cursor will move to the beginning of the line.
