If the button or cursor point is being used to ramp a value at the Value connection:
 When the tag assigned to the Value connection is an integer tag, but the ramp value is

begins timing. For details, see page 21-12.

There is no Delete button in the pop-up keypad, but you can use
the Delete key on an external keyboard or keypad.
