Shared lists are a quick and efficient way of dealing with single and multiple choice responses that are common to a number of questions. A typical example might be a five-point rating scale that you want to use for rating various aspects of product. Rather than retyping the five responses for each question, or copying and pasting them from one question to another, you can set them up as a shared list with a unique name and then insert them as a block wherever they are needed.

Shared lists are shown at the end of the Overview tab under the heading Shared Lists.
