THE UNDOCUMENTED FILL SHORTCUT

There are all sorts of keyboard shortcuts for filling selections, entire layers, and stuff like that, but if you look under the Edit menu, next to the Fill command, there doesn't appear to be a shortcut for bringing up the Fill dialog itself. Luckily, there's an undocumented keyboard shortcut that will do the trickit's Shift-Delete (PC: Shift-Backspace). This is a good one to pull on your Photoshop buddies and coworkers as a Photoshop trivia question, because few people know it exists.
