Answer 1

Not sure if it's a bug but YES you can remap it. However the behavior is a little different from that in Xcode 3. You can set it to Cmd+alt+up /down in Preferences. Note that you can't set the alt key on "Jump to Next Counterpart" but only "Jump to Next Counterpart (option)". This new key binding will open implementation/interface file in Assistant Editor side-by-side with the original editor.

Cmd+Return to close the Assistant Editor.
