How to search Xcode4.2 project?

I'd like to run a search on all files in my project. How can this be done in Xcode please?

Solution

In Xcode 4, as Jano mentioned:

⌘3 (Command + 3) will show the Search Navigator

However:

⇧⌘F (Command + Shift + F) will open the Search Navigator with focus on the search field

Both of these keyboard shortcuts will bring open the panel you need to search in all files. This page on developer.apple.com shows a list of the keyboard shortcuts available in Xcode.

From that reference, the following are the other Find related shortcuts:

Find in Workspace…             ⇧⌘F  (Shift-Command-F)
Find and Replace in Workspace… ⌥⇧⌘F (Option-Shift-Command-F)
Find…                          ⌘F   (Command-F)
Find and Replace…              ⌥⌘F  (Option-Command-F)
Find Next                      ⌘G   (Command-G)
Find Previous                  ⇧⌘G  (Shift-Command-G)
Use Selection for Find         ⌘E   (Command-E)
Use Selection for Replace      ⇧⌘E  (Shift-Command-E)
