Ruler

 

A ruler (see figure 4.7) is used to control various values.

Figure 4.7: Ruler

A ruler is used just like a slider. The additional buttons (arrow left/right) set the value step by step, if pressed more than half a second, repeatedly. The step size can be changed in the configuration layer of the ruler (see figure 4.8).
