You can use the Logitech Spotlight Presentation remote and Logitech Presentation Software to adjust the volume and to scroll through web pages or applications.

NOTE: If you don't have Logi Options+ installed, you can download it from logi.com/optionsplus.

For example, you can adjust volume by doing a long press of the Back or Next button:

1. Launch the Logi Options+ App.
2. In the Hold Back menu settings, select Volume.
3. Press and hold the Back button while moving your hand up and down to control the volume. 

   

4.  

   The Spotlight motion sensors will sense the movement and adjust volume accordingly.

The scroll function works similarly, using motion sensors to adjust the speed of the scrolling, and can also be assigned to a long-press of the Back or Next button.
