The RSS Screensaver template provided with Quartz Composer is nice --
but it does not show how keyboard input can be handled to open a URL
(like the OS X RSS Screensaver provided by Apple does).
Opening the Apple RSS Screensaver, I noticed the keyboard output from
the composition is sent to an output called "launchURL" -- but this
doesn't seem to work when placed in other compositions.
Any ideas regarding a way to "launchURL" from a QC composition?
