The Command Bar, a series of black buttons usually displayed on the bottom left of an object, provides quick access to any additional functions that can be activated on the object (e.g. such as annotating).
The Command Bar becomes visible when a document/object is touched. The Command Bar will fade out and become hidden after a short period of inactivity. Touching on the document/object again will make the Command Bar reappear.
The most common Command Bar function is to activate the annotation mode, or to change navigation modes on the web browser.
