The Chrome OS launcher — the drawer-like interface that appears when you tap the Everything key (a.k.a. the Search key or Launcher key) or when you hit the circle icon in the lower-left corner of the screen — is actually a powerful universal search tool. Just start typing as soon as it appears, and you can find and open apps, pull up websites, and even get answers to specific questions right then and there — no clicking or digging required. The launcher has some easily overlooked extra powers, too. Try typing in calculations like 172.4/3, for instance, or unit conversions like 14.9 feet to meters to put Google to work at the system level.
