    Extends NumberTextBox to add up/down arrows and pageup/pagedown for incremental change to the value

  • description

    A `dijit.form.NumberTextBox` extension to provide keyboard accessible value selection
    as well as icons for spinning direction. When using the keyboard, the typematic rules
    apply, meaning holding the key will gradually increase or decrease the value and
    accelerate.
