Adjustment Brush Resize Tricks
*Adobe Bridge CS4 and Adobe Camera Raw 5 Tip*
When using the Adjustment Brush for retouching, you need to change the size of the brush quite often. You can use the Left and Right Bracket keys ( [ ] ) to make small incremental changes to the brush size, but the mouse scroll wheel is the quickest way to resize the brush. If you're using a Wacom tablet (highly recommended), you can still use the mouse scroll wheel. Place the mouse where you can reach it with your free nonmouse hand and use both together.
