Click on any free place in the Graphics View to create a slider for a number or an angle. The appearing dialog window allows you to specify the Name, Interval [min, max], and Increment of the number or angle, as well as the Alignment and Width of the slider (in pixels), and its Speed and Animation modality.
- Alt-O (Mac OS: Ctrl-O) for the degree symbol °
- Alt-P (Mac OS: Ctrl-P) for the pi symbol π
The position of a slider may be absolute in the Graphics View (this means that the slider is not affected by zooming, but always remains in the visible part of the Graphics View) or relative to the coordinate system (see Properties Dialog of the corresponding number or angle).
Like other objects, sliders can be fixed. To translate a fixed slider when Move Tool is selected, you can drag it with your right mouse button. When Slider Tool is selected, you can use either left or right button. Sliders made with the Slider Tool are fixed by default (from GeoGebra 4.0). You can change value of fixed slider by simply clicking it. Preview of the new value appears next to your mouse pointer.
