IE10 / IE11 Metro mode: How to switch tabs or show the address bar

Internet Explorer on Windows 8 and 8.1 is available in a "Desktop version" and the metro version which is designed for touch devices. \
When using IE Metro with a mouse (e.g. via BrowserStack), controls such as the tab bar or address bar will disappear after a little while.

To show them again, right-click anywhere in the page (except on links, etc).
