Open Up Some Screen Real Estate
A lot of times when you’re working on a project, your screen can get really cluttered with palettes (Photoshop is an especially palette-heavy application). If you want all the palettes out of the way for your convenience while you’re working, just press Shift-Tab to hide them, or Shift-Tab to bring them back. The menu bar, the Options Bar, and the Toolbox will still be visible.
