10.6: View debug info about current desktop picture
Wed, Nov 4 2009 at 7:30AM PST • Contributed by: Joe OReillyWithin the Desktop & Screen Saver System Preferences pane, pressing Command-Option-D (Show/Hide Dock shortcut) will add two new buttons to the panel: TEST and DEBUG WINDOW. Press Command-Option-D again to remove the buttons. TEST doesn't seem to do anything, but DEBUG WINDOW displays a window that gives you debug information about the current desktop picture.
hmmmm hidden buttons
