Ok, Ok, i know in gchat the orange clock means idle, thats pretty easy to figger out. but what does idle mean, does it just pertain to lack of activity on gchat or lack of activity on any gmail functions or lack of activity on any google function or lack of activity on any app on the computer? anybody know?

It means that you haven't used your mouse or keyboard for a certain amount of time
