10 Chapter 1: Operating the TIN73 Entry Line The entry line displays all characters selected in the Text editor. The entry line also accepts all number keys (Y, Z, [, …) and many keyboard operations (6, I, \, C, etc.). Enter these between Text editor characters, as necessary, without leaving the Text editor. If you press a key that isn’t accepted in the Text editor, the calculator does not return an error. You must select Done to exit and then continue your entry on the previous screen. You can enter up to 16 characters on the entry line. If you need to enter more than 16 characters, select Done to save your entry. Then reenter the Text editor, and continue entering additional characters.
