•Modification made to Comments are automatically saved whenever you exit the Comments Editor, or save the current script.
•The comments' text can have attributes such as bold, underline, italic, color and size. To set attributes for a text selection, select the text, and then right click on the comment editor. A popup menu appears letting you set, or un-set, attributes for the selected text.
This can be a running "to do" list or comments, in case someone else opens your script and needs to understand something you have done.
