Beans can be selected singly and one after another by clicking the mouse
To select more than one bean, the Ctrl + Shift keys should be kept pressed while clicking on the components.
Another way to select more than one component is to press the Shift key
while you "lasso" the components with the mouse (click with the mouse
and
draw a frame around the components). When you release the mouse button, all the
components in the frame will be selected.
In the Component tree individual Beans can be selected. With pressed key further components can be selected. With pressed key the entire range between the Beans in the Component tree is selected
