-Copy Text from Quick Look

Quick Look is one of OS X's best features. Just hit the Spacebar when you select a file, and you'll see a preview of that file without having to open up an app. It's great, but you can't select any text when you're in the preview. You can add that feature with a Terminal command: defaults write com.apple.finder QLEnableTextSelection -bool true killall Finder Now, just open up Quick Look, select the text you want, and copy away.
