Pausing For A Brush Preview
If you’re choosing your brush tips from the expanded Brushes palette, you don’t have to actually click on a brush to see the large preview of it at the bottom of the Brushes palette (which is nested in the Palette Well by default). Instead, just pause your cursor right over the brush you want to preview, and in just a second the preview will appear, even though you didn’t actually click on the brush tip. The catch is: The Show Tool Tips checkbox must be turned on in the General Preferences for this “pause preview” to work.
