8.2.1 Reviewing the Calculation.
If you are not sure that you have entered a calculation correctly, you can review the calculation
before pressing ENTER.
Pressing the PREVIOUS thumb key moves the Braille display back, that is to the left, one cell at a
time. Pressing the NEXT thumb key moves the Braille display forward, that is to the right, one cell
at a time.
After pressing ENTER to complete the calculation, pressing the PREVIOUS and NEXT buttons
together toggles between displaying the result and the details of the calculation.
When using speech , there are two review commands available before pressing ENTER. They are:
To review the whole calculation, press READ with I.
To review the last number or operator entered, press READ with K.
8.2.2 Editing the Calculation.
While entering a calculation you can backspace to delete entries one-by-one by pressing
BACKSPACE or CONTROL with M, one or more times.
If the current calculation started with the result of a previous one, BACKSPACE does not delete
that number, because it was calculated rather than typed. Entering a new calculation clears the last
result.
8.2.3 Calculation Entry Errors.
When you type a calculation, KeyPlus beeps if you make a mistake, such as: 3 + *
Press HELP to find the reason. In this case, KeyPlus displays: "Value expected."
Other messages indicate different errors. You may want to review the calculation after an incorrect
entry, by pressing READ with I to find out where you are.
