How do I change the calculator layout from a 10-Key to a handheld in 10-Key Plus?
To change the layout of the calculator from 10-Key to a handheld calculator, select the “Handheld Calculator” from the Options Menu. Alternatively, you can use the F3 hotkey to change the layout. To return to a 10-Key layout, select the 10-Key Calculator from the options menu or press the F2 hotkey. A checkmark will indicate the current calculator layout setting.
