Sure. For example, if you are using a text editor with annotation features. You can use the highlight function which is separate from the text content itself. It's like putting a virtual marker on the text without changing the words of the story. So it's possible to add a highlight without adding to the story.
Yes, you can use formatting tools like bold or italicize specific parts of the existing text to create a highlight without actually adding new content to the story.
Yes. You can use a thin, transparent sheet of plastic or vellum placed over the page to mark the area you want to highlight without writing on the book's pages or changing the story in any way.
One way is to emphasize existing elements through unique formatting. For example, italicize key phrases or put important parts in a different font size. This catches the reader's attention without adding to the plot.
Another approach could be using a highlighting pen or marker on a printed copy if it's a physical document. But this is a very traditional method. If it's a digital file, perhaps use a dedicated highlighting tool that has an option to keep the highlights in a separate layer or file. For example, some PDF readers allow you to highlight text and save those highlights separately from the actual PDF content which represents the'story'.
Yes. Posting a highlight alone can be useful if it's a self-contained, significant event or aspect that doesn't need more story elements to make sense.
I don't think it's possible. A highlight usually involves emphasizing or featuring certain parts of the story, and that kind of selection can feel like an addition in a way.
