Invokes an on-line documentation. In addition to selecting menus from the menu bar, the mouse can also be used to perform a number of actions. Left button Clicking on an object's folder symbol, name or icon selects the object. Double clicking on the object's folder symbol places the object on the lab table by invoking the object manager on the object. Double clicking on the object's name shows or hides object extensions.
Middle button Selects an object and makes it possible to copy it using the drag and drop operation.
The user selects an object and drags it to a new location, where a new child is created. The view of the object hierarchy is automatically scrolled if the destination object is located outside the viewing area. Drag and drop operation only copies the object, not the object's extensions. Its functionally is equivalent to performing Copy node and Paste operation. Dropping an object on itself or releasing the mouse button with no object selected cancels the drag and drop operation.
