What is the special search key on my Acer Chromebook?
The Chromebook comes with a special search key to help you quickly search the web. Whenever you press the key, a new tab opens. Enter what you're looking for in the address bar, then press Enter to immediately see search results from your default search engine.
Note: To make room for the search key, we took away the Caps Lock key. But if you really need to use Caps Lock, go to the Settings page to make the search key act like a Caps Lock key. Learn more about changing modifier keys
