virtual devices

[iberium]

I was working on creating a few custom remotes as I need the color buttons and a few others.  I have watched the screen casts and have noticed that there are several virtual devices that are referenced (ex. -106).  Is there a way that I can reference what these virtual devices are?  My 106 device is my screen saver so I know this is incorrect.  Just trying to learn the ins and outs better.

106 != -106

for details on virtual devices look at the virtual devices article in the wiki.
