Bookmarks
Power Prompter features a bookmark system that allows you to mark and then quickly access places within your scripts.
Creating bookmarks
You can bookmark a location in your script by moving the text input marker (cursor) to the location where you want to add the bookmark and then select Bookmarks 
Insert Bookmark (⌘K).
You can also prepend a * (asterisk) to the beginning of a line to quickly bookmark a location in your script.
Note
You should add bookmarks using the * (asterisk) option only at the beginning of a paragraph to prevent Power Prompter from moving the bookmark around when re-arranging the script to make it fit the words/line setting.
Deleting bookmarks
You can delete bookmarks either directly from the bookmarks sidebar by right-clicking on a bookmark and selecting from the context menu or by moving the text input onto a bookmark and using Bookmarks Delete Bookmark (⌘K).
