Adjustment Brush resize tricks
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 recom-mended), 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.
