Editors in the publishing field use the caret symbol to indicate that there is a section on the page where something is missing. For example, if a word is misspelled because it lacks a needed letter, the editor can insert a caret with the needed letter just underneath it. You can also use carets to mark long vowels in some languages, such as French and Portuguese.
