Hi Jim, “clicking” is already implemented. Whenever the LED pen is on and detected by the software, the mouse is moved to that position and a left button mouse-press is executed. The mouse button is released when you turn off the LED pen. I actually implemented right button mouse-clicking today. A right click is executed when the LED pen remains on at the same position for a certain amount of time (e.g. 1 second).
Concerning software keyboards: KeyStrokes and VirtualKeyboard are two that I found with a quick search.
