A stepper lets the user incrementally increase or decrease a numeric, date, or time value. For example, when editing text in a Keynote presentation, steppers let you adjust a variety of text attributes including the point size, spacing around paragraphs, and bullet indentation. A stepper usually resides next to a field that displays its current value.
