If you begin dragging with the Move Selected tool on a blank area of the map, it will behave like the Select tool, which lets you quickly drag over items to select them, and then drag them to a new position, without having to switch between the Select and Move Selected tools.
To rotate items, do the following:
Right-click on the map at the intended point of rotation, and click Set Active Point
Select the items you want to rotate and switch to the Move Selected tool.
Hold the Alt key and drag the Move Selected Tool left or right to rotate the selected items around the Active Point.
Release the mouse button when the selected items are in their new locations.
