You can call it by sliding the left edge to the right, similarly, there are similar menus on top, bottom, and right. The HOME or BACK key is not added to the Panel. Mark Shuttleworth of Ubuntu indicates that the limited screen should be used as efficiently as possible. Another major selling point is support For HTML5, which means Apps on Firefox OS can also be used on Ubuntu For Phone in principle to lower the development threshold.
