When entering a new field value, by pressing and holding the key for 3 seconds the value will be
incremented by the next magnitude. For example, if the current value is 100.0, every pressing of the
key increments the value by 0.1. After holding the key for 3 seconds, the value will begin to increment
by 1. After holding the key for another 3 seconds, the value will increment by 10, and so forth.
Similarly, holding the key for 3 seconds will decrement the value by the next magnitude.
