© Insert/Delete Key ( cn
This is another convenient key for correcting displayed characters. When it is
pressed directly, the characters following the one under which the cursor is
blinking are moved to the right so that a space can be created for character
insertion. The cursor itself does not move.
When
GG are pressed, the character under which the cursor is blinking is
deleted and the characters on its right are moved to the left. The position of the
cursor remains unchanged.
Continuous insertion and deletions are possible by keeping (#5 and 125 pressed
respectively.

play is out owing to AUTO POWER OFF (see page 12), power is turned on again.

The characters to the left of the cursor can be deleted continuously by keeping
this button pressed.

When pressed during program execution, this temporarily suspends program
