Scale controller Clause Samples

Scale controller. You use the scale controller to enlarge or reduce the displayed map. When you move the scale con- troller downwards, the scale of the displayed map is enlarged and a more detailed map is displayed. Conversely, moving it upwards reduces the dis- played map, and a wider area is displayed. Also, when a list is longer than one screen, this control- ler is used for indicating the next screen or previ- ous screen.
