Hi, I leave my Air on pretty much all the time, and put it to sleep while moving around etc. Sleeping it disconnect the Airport connection - which if very annoying. At a desk I've just been dimming the display all the way off in order to keep my connection. However, I recently noticed that by setting a "sleep display" hot corner, my network connection is maintained. I have 2 questions: 1) Is sleep display equivalent (functionally) to simply dimming the display all the way down? 2) Is there a way to either set up a shortcut to sleep the display (other than a hot corner) and/or set it so that only the DISPLAY sleeps after 'x' minutes? Thanks in advance!
