Easily Add Applications Or Files To The OS X Dock Or Sidebar With Keyboard Shortcuts
The OS X Dock and Finder Sidebar are both excellent ways of gaining access to your most frequently used files, folders, and applications. While there are numerous ways of getting new items into these locations, the keyboard shortcut is often the fastest and easiest way.
So, if you are a fan of the Dock or Sidebar, and are continually updating its contents, you’ll want to commit this tip to memory.
To add an item to the Finder’s Sidebar, select the item and press Command+T. To add an item to the Dock, press Command+Shift+T.
Caveat: Hitting Command+Shift+T while in a web browser will open up the last closed tab.
