Command-shift-D equivalent for Xcode 4?

I'm trying out the Xcode 4 beta, and I'm really missing ⌘-Shift-D, w开发者_StackOverflow中文版hich lets you search for symbols or files and open them quickly. Does anyone know how to invoke it in Xcode 4?

⌘-Shift-O

Command-Shift-O is the new "open quickly" keyboard shortcut in XCode 4. "O" for open I guess...

In Xcode 3 you can command-doubleclick a symbol to jump to its definition. A future version of Xcode which is under NDA may provide very similar functionality.
