Keyboard: CTRL + SHIFT + V; CTRL + SHIFT + INSERT
Menu: Edit -> Cycle Clipboard Ring
The Clipboard Ring keeps track of the past 20 items you've either cut or copied so you can reuse them over and over again! After you hit item 20, it'll go back to the first item again. This is why the feature is called a Clipboard Ring.
Give it a try! Copy a few pieces of text into your clipboard then keep pressing CTRL + SHIFT + V to cycle pasting them in the editor. This is one seriously cool time-saving feature.
