Editing a Calculation
A Insert Mode and Overwrite Mode
The calculator has two input modes. The insert mode inserts your input at the cursor
location, shifting anything to the right of the cursor to make room. The overwrite mode
replaces the key operation at the cursor location with your input.
Only the insert mode is available when natural display is selected as the display format. You
cannot change to the overwrite mode. When linear display is selected as the display format,
you can choose either the insert mode or overwrite mode for input.
