How to quickly cycle through "Scale" options

The scale tool has three different modes, each one working a little different. But, did you know that you could quickly cycle through all three modes with the press of a button?

Select and Uniform Scale
Select and Non-Uniform Scale
Select and Squash

How to cycle through the modes:
Press the "R" key multiple times. The first time you press it, it will switch to the Scale tool and whatever mode it was last on. The next time you press the "R" key, it will switch to the next mode. "R" is the default hotkey for the Scale tool.


Select and Uniform Scale:

The Select And Uniform Scale button, available from the Select And Scale flyout, lets you scale objects by the same amount along all three axes, maintaining the object's original proportions.

Select and Non-Uniform Scale:

The Select And Non-Uniform Scale button, available from the Select And Scale flyout, lets you scale objects in a non-uniform manner according to the active axis constraint.

Select and Squash:

The Select And Squash tool is useful for creating different phases of the “squash and stretch”-style animation often found in cartoons. The Select And Squash tool, available from the Select And Scale flyout, lets you scale objects according to the active axis constraint. Squashing an object always involves scaling down on one axis while simultaneously scaling up uniformly on the other two (or vice-versa).
