One of the little features Adobe added to InDesign CS5 is something that’s been in Photoshop for a long time, and just makes rotating objects a little easier.
Rather than selecting your object and using the Rotate tool in the Tools panel, simply move your cursor to just outside the corner of your object with the Selection tool to reveal the hidden rotate icon – then just click and drag the mouse to rotate.
Of course if you’re looking for a keyboard shortcut, you can always just hit the R key to select the Rotate tool without visiting the Tools panel.
Either way, you can rotate multiple objects without grouping them – yet another time saver!
