Spaces in 10.5.3
One non-obvious detail is that you can switch to another space by clicking an app’s Dock icon multiple times. If you click a running app’s Dock icon once, that app will activate in the current space. If it doesn’t have any open windows in the current space, it will activate without creating a new untitled window. But if you click that same app’s Dock icon again, you’ll jump to the next space in which that app does have an open window.
