Menu: Window Showing/Hiding Brushes
This tip works in Photoshop 5.5 and 7.0, as well as ImageReady 2 and 7. In Photoshop 6 and ImageReady 3, the Brushes palette was replaced by the Options bar. When you select a painting tool, the Options bar will display the Brush options for the selected painting tool. Photoshop 7 and ImageReady 7 reintroduced the Brushes palette along with its old shortcut, F5.
