Collapsing and Expanding the Floating Palettes
When you first open Photoshop, several additional floating palettes are stacked along the right edge of your screen in 4 separate palette groups. The first group contains the Navigator, Info, and Histogram palettes. Next is the Color, Swatches, and Styles palettes. Below that are the History and Actions Palettes. Finally, you have the Layers, Channels, and Paths Palettes.Palette groups can be moved around in the workspace by clicking on the title bar and dragging. Each palette group has a collapse and a close button in the title bar area. Try the collapse button for each of the palette groups now. You'll notice the button works as a toggle, clicking the button a second time after the palette is collapsed will expand the palette again. You may also notice that some palettes do not completely collapse when you click this button. Try collapsing the color palette and you'll see that the color ramp is still visible.
For palettes that partially collapse, you can completely collapse them by holding down the Alt (Win) or Option (Mac) key as you press the collapse button. You can also collapse a group by double clicking on any of the palette tabs. To display a collapsed palette, just click once on the palette tab if it's in the back of the group, or double click if it's in the front of the group.
