These functions include TABSET (6 letters), which allows users to set tabs for text alignment; EDIT (4 letters), which allows users to make changes to the document; UNDO (4 letters), which allows users to UNDO any changes made; and SPELLCHECK (10 letters), which checks the spelling of words in the document.
