When you work with container shapes, dropping a shape over that container inserts that shape into that container.

You can quickly build flow charts, mind maps or tree diagrams using shortcut key combinations.
When you drag a selection box around too many shapes, you can either do it again to include the shapes you wanted to select, or use hold down `Alt+Shift` and drag a deselection box around those shapes that you don't want to include in your selection.
