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