Today is a quick tip that allows you to open items in your recently accessed menu bar option within Finder. When you go to the Apple Menu bar option > Recent Items you are given a list of your recently opened apps and files. When you select one of these items it will open the file in the default app. However by pressing the command key the menu item will change. It will now instead display an option asking you if you want to open the file or app within Finder.
This is very useful. Instead of opening the files within the app you can see the Finder window in which they belong. This is great if you want to alter the file within Finder, or find out where it is stored.
