Anyone who has to explain something that is visible on a screen can use a laser pointer or pointer, but the possibilities of such aids are limited. Demohelper is a program that has a lot more to offer for computer demonstrations. With Demohelper you can zoom in on the screen statically but also dynamically (Live Zoom) where you can simultaneously use all kinds of annotation functions. This allows you to mark screen parts in different colors, draw arrows and so on. In addition, the program shows which keys you press and which mouse buttons you use.
