What is “drag and drop”?

To drag the window to the containers bar, follow these steps:

1. Place the mouse at the top of the window, on the bar its name is shown.
2. Keep the left button pressed and move the pointer until you place it on the containers bar. If the container where the window is opened is not organized as "Columns", we must press the "Control" (CTRL) key while we take the window to the containers bar.

You will see that when you start dragging the window to create the new container, the mouse pointer changes 
To add a new container directly, do as follows:

1. Right-click on the tab of an existing container. A menu is displayed.
2. Choose the option "Add Container". A container tabbed "New Container" is added and a window appears so as to choose its properties.
3. Enter the container's properties.
4. Confirm creation of the new container clicking on the "OK" button or quit the operation with the "Cancel" button.
