A toolbar provides ready access to the grouping tools: Group, Ungroup, Make Unique, and Edit (these tools also appear on the Context Menu). The Toolbar tools let you choose an action first, followed by the object on which you want to execute the action. The Context menu reverses this order (at the cost of one extra click): You choose an object first and then choose an action to perform on that object. This action/selection order makes Toolbar Edit the better choice to edit nested groups. You can also use keyboard shortcuts: G, E, F (Group, Edit, Finish) plus U (Ungroup) and M (Make Unique).
