Insertion indicators, also known as carets, are symbols used to indicate where text should be inserted in a document. They are commonly used in word processing programs and other software applications. Carets are usually represented by two vertical lines pointing up and down, and can be used to indicate where new words, phrases, or sentences should be added. Carets can also be used to indicate where a specific character should be inserted, such as a punctuation mark or a space. Carets are an important tool for editing documents, as they help to ensure that the text is correctly formatted and that all changes are accurately tracked.
