k Using Undoing and Redoing Operations

You can use the following procedures during calculation expression input in the Math input/
output mode (up until you press the

w key) to undo the last key operation and to redo the

key operation you have just undone.

- To undo the last key operation, press:

aD(UNDO).

- To redo a key operation you have just undone, press:

aD(UNDO) again.

• You also can use UNDO to cancel an

A key operation. After pressing A to clear an

expression you have input, pressing

aD(UNDO) will restore what was on the display

before you pressed

A.

• You also can use UNDO to cancel a cursor key operation. If you press

e during input and

then press

aD(UNDO), the cursor will return to where it was before you pressed e.

• The UNDO operation is disabled while the keyboard is alpha-locked. Pressing

aD(UNDO) while the keyboard is alpha-locked will perform the same delete operation
as the

D key alone.
