Used to select general usage element selection, manipulation, and modification tools.

The tools in the Main toolbox are also members of a "child" toolbox. When a tool is pointed to and the Data button held down, its child toolbox opens. When a tool is pointed to and the Data button held down, a drop-down menu opens from which a tool in the child toolbox can be selected. The child toolbox can be "torn off" and floated by choosing Open As ToolBox from the drop-down menu.

When a tool is selected in a child toolbox (attached or floating), the tool automatically becomes the "representative" of the child toolbox in the Main toolbox.

All tools in a toolbox are not always visible by default. To see all tools, right-click in the toolbox and select Show All from the menu.
