### Why is this important?
Changes in context can confuse or disorient users who cannot easily perceive the change.
If activating a link opens a new popup or a window, informing the user in advance helps people who use assistive technologies be aware of the change in context.
<!-- This is where the code snippet is injected -->
<div id="locSnippet"></div>
### What to do
* Include a warning in the label advising the user that the link opens in a new window
* **Or**, use CSS to provide a warning before opening a new window (see Example 2 in [WCAG technique G201](https://www.w3.org/WAI/WCAG22/Techniques/general/G201))
