Note: I rely on your feedback about bugs and issues you may encounter with Valence. Please drop me an email if you have any problems, and let me know which VNC server software you are using. Mentioning problems in reviews is not sufficient, since I can't respond or ask more questions about the problem.
The inspiration for Valence was a need to control a home theater PC from the couch, but it can be useful in any situation where a computer doesn't have a keyboard and mouse handy. Your computer must be reachable over the network from your Android device, and be running a VNC server.
Valence now supports right-clicking (by tapping with two fingers at the same time) and scrolling (by swiping two fingers up and down).
For more information about using Valence and configuring a VNC server on your computer, follow the website link below or view the online help (Menu->Help).
