Where is set the active build configuration in Xcode 4

Question

I have 3 configurations in my project (Debug, Distribution_AdHoc and Distribution_AppStore). In Xcode 3 we had a list to choose device, version, configuration and target before build and run. Now with Xcode 4 we only have the device kind and version in this list. This bring my two questions:

1. So where is defined the configuration used ? Is that the configuration defined in "Project > Info > Command-line builds use: Debug" ?

2. And now the "Project" menu is replaced by "Product" So where can we create (or duplicate and edit) a Configuration ?

Thank you.

Answer 1

Just in case you still want to make a Distribution config (or other config--I still find them useful), after great length (read: searched in the help for 'duplicate'), I found this:

At first, they were all grayed out; this was because I had one of the targets highlighted in the editor (MFE, MFETests, etc.). If you highlight your project (as in the screenshot), they become enabled.
