Change the formatting of a specific sentence or word in your book

Tell it which text you mean by copying the sentence exactly as it appears in your book, and what you want: bold, italics, underline, a color, a different font or a different size. Gutter finds that exact text and changes only its formatting.

If the sentence appears more than once, you can say which one: the first, the second… And if the text you give it isn't in your book, it lets you know instead of making things up.
