Below that is 1-1: and when 123 is entered i appears in cell 1-1.

How to get out of spread sheet mode?
Thanks very much, Brooke

What you're seeing is the built-in Matrix Writer. On a 48GX, that is normally initiated by pressing right-shift then the ENTER key. To exit without saving the matrix contents, just press the ON key by itself.

If you've created a matrix that you wish to use, just press the ENTER key while the matrix is displayed onscreen. The matrix will be added to the stack in level 1.
