Do you use a lot of smart playlists in iTunes? Are you constantly tweaking them to get them just right? If so, here’s a quick way to edit them—quicker even than using the control-click contextual menu.
Just option-click on the smart playlist you’d like to edit, and the edit window will instantly appear. You don’t even need to select the playlist first—when you option-click, iTunes will move the selection to that item, and then open the edit window. Option-clicking on a standard playlist does nothing, as there’s nothing there to edit.
And before you ask—yes, this shortcut still works in the just-released iTunes 7.
