Where is the basic Control-TAB (MRU) behavior in Xcode?

Question

In most multi-document editors for windowing environments, Control-TAB will utilize an MRU list to bring the user back to the last visible file. What

Answer 1

In recent XCode (10.3), when in a code editor press:

ctrl+1, right, right

Then use up and down keys and enter to select from the MRU sorted list of recent files.

There is even an option to increase the size of the history.

Answer 2

As of Xcode Version 3, there isn't anything that's exactly like the MRU you describe - however, check out the discussion on this page for some options that will get you closer to the behavior you want.

Answer 3

In Xcode 3 (or any Mac application) you can use Command-Tilde (⌘~) to switch between open windows.

In Xcode 4 you use ⌘} for next tab and ⌘{ for previous tab - command shift bracket.

As a side note, for some reason Xcode 4 won't let me set the key binding for previous/next tab to the standard Control-Tab. When I try it puts in Command-Control-Tab.
