What it is
Two quick taps on the same region that trigger a secondary action. Use an established convention such as zooming and keep the action available through a visible control where practical.
When to use it
Use it for familiar content interactions rather than essential undiscoverable commands.
Know the difference
Double tap requires two contacts; long press depends on contact duration.
