## page-increment

Arguments: scroll-bar-mixin

Returns the value of the page-increment property of its argument. This property determines the distance a slider will advance when the PAGE UP or PAGE DOWN keys is pressed.

Used by the PAGE UP and PAGE DOWN keys, or when you click inside the body of the scrollbar between the scroll arrow(s) and the slider. It contains a numeric (fixnum) value relating to the range. If the range is (0 100) and the page-increment is 10, then pressing a PAGE UP or PAGE DOWN key will advance the slider 10/100 of the way along the dialog in that direction.

PAGE DOWN in a horizontal `trackbar` or `horizontal-scroll-bar` moves the slider to the right, and PAGE UP moves the slider to the left.
