Some longer novels may have lots of characters in the storyline. Sometimes these characters are introduced in the first few chapters, but then disappear until the end of the novel for their comeback, or they may have only a small, but critical role.
Occasionally I forget who these characters are
so I have to scroll back to remind myself.
Is there any way to annotate the name of the character throughout the book?
ie, Marcus is introduced in the first chapter. I make a note about his character-
"Lawyer at Bendini and Lambert, defending the protagonist John". Then every single instance of the word "Marcus" in the novel is linked to that note and I can call up the annotation from anywhere in the book the word Marcus is mentioned.
This would need to be edited into the ebook. Is it possible?
