Resetting the Work Area Background in Photoshop

Somehow when speeding around and keyboard shortcutting and clicking in Photoshop, I accidentally changed my Photoshop work area background color. Not what I wanted! Here's how to set it back to its original color. This tip works for full-screen mode too.

1. The default gray background that Photoshop ships with is R: 204 G: 204 B: 204. Enter this color in the Color Picker as your foreground color.
2. Select the paint bucket. Expand the image window if necessary and shift-click on the background area you wish to change.
