Sticky Mode: Double-click a drawing tool’s button on the left panel before beginning to draw. When the object is completed, the same drawing tool will remain selected and more objects can be drawn with the tool. To escape this mode, press ESC on the keyboard, and the previous navigation tool will be selected. A green dot on the tool’s icon indicates that the tool is currently in sticky mode. Single-clicking the tool’s icon again will turn off sticky mode but keep the tool selected.
At any time while drawing, the user can press escape, which causes the current object to be cancelled and the previous navigation tool to be selected. For each tool there are often two ways to create its object. One way is to draw the object graphically using the mouse and keyboard. The other is to interactively create the object by typing information such as coordinates, widths, etc. in the tool’s property panel. The property panel will update the graphical preview immediately to reflect changes in the input. This allows fine-grained control in creating the object. The individual drawing tools are discussed in the next section.
