GETTING BACK TO THE FILTER GALLERY DEFAULTS

Let's say you've tried all the filters in the Filter Gallery, and changed each setting so much that you can't remember what the default, out-of-the-box settings were. Well, you're out of luck (kidding). Here's a trick for getting back to those default settings for any filter the Filter Gallery supports (like any of the Artistic filters, the Sketch filters, etc.): Open one of these filters (by choosing it from the Filter menu) and when it opens in the Filter Gallery, press-and-hold the Command key (PC: Control key) and you'll see that the Cancel button changes into the Default button. Click it (while still holding down Command/Control) and the default settings will magically reappear.
