Hate the new resume feature and how you end up with a bunch of old windows/tabs open when you launch Safari, QuickTime, or any app that uses Lion's new resume feature? Well a simple three button keyboard shortcut will save you all the trouble: ⌥ + ⌘ + Q (thats Option + Command + Q) Simply press these keys when you want to quit an app and the next time you open it, the last opened windows/tabs will not be resumed and you will start with a fresh app. This should (hopefully) be a great tip for those who want more control over the resume feature that has been introduced in Lion. You can also see this option appear in the app's menu where "Quit" normally appears by holding down the option key. This hotkey should work with any app that supports Lion's new resume feature, though I have only tested it with a handful of them. For me it seems just as easy to press as CMD + Q normally is, so I think it shouldn't be too difficult for everyone to learn to use.
