The Drawing Toolbar, located on the left side of the screen, contains all available drawing tools for adding to or manipulating the current drawing. The tools and their exact functionality are detailed in the following sections; however there are some general concepts of the toolbar that need to be discussed first. All tools with the exception of the Move, Zoom, and Selection Tool can operate in two modes: "Normal" or "Sticky".
In Normal Mode, which is activated by selecting the tool through a single tap, the tool is used to insert one figure into the drawing. Upon completion of creating a figure, the Move, Zoom, and Select Tool will be reactivated and the created figure is selected. A tool is in Normal Mode when it's background is highlighted with a blue gradient as shown in the first figure below.
Sticky Mode, which is activated by selecting a tool by a double tap, makes it possible to add many figures into the drawing without having to reselect the tool. Upon completion of creating a figure, the tool will remain selected, and additional figures of the same type can be created/inserted immediately. To cancel/end creating the selected figure type, simply select another tool. A tool is in Sticky Mode when it's background is highlighted with a blue gradient and contains a lock symbol in the lower right hand corner as shown in the figure below.
