Main toolbar > Select and Scale flyout

Right-click an object. > quad menu > Transform quadrant > Rotate

Edit menu > Scale

The Select And Scale flyout on the main toolbar provides access to three tools you can use to change object size. These are, from top to bottom:

Select and Uniform Scale

Select and Non-Uniform Scale

Select and Squash

In addition, the Scale command is available on the Edit menu and the Transform quadrant of the quad (right-click) menu; this activates whichever scale tool is currently chosen in the flyout.

Note: The Smart Scale command activates the Select And Scale function and, with repeated invocations, cycles through the available scaling methods. By default, Smart Scale is assigned to the R key; you can use Customize User Interface to assign it to a different keyboard shortcut, a menu, etc.
