I have a section with the title in the picture. If I don't put the hyphen manually, the word ultimo does not get hyphenated and stays on the first line, producing an Overfull \hbox. But as you can see, the manually put hyphen goes into the toc which is not nice. Is there a way to mark a hyphenation point or to insert a hyphen that will be put in only if the line breaks immediately after it?
PS In case you're wondering, the blue italic text conceals a link. I decided to highlight links that way. Any advice on that is welcome, though not properly on-topic in this question :).
