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.
Open the document in which you want to include the caret.
Locate the "caret" symbol on the keyboard. This symbol shares a key with the number "6."
Press "Shift" and "6" and the caret appears.
