How to toggle between .h and .m in Xcode 4

Question

Just installed Xcode 4 so far so good, except that Apple changed all the keyboard shortcuts! Anyone know how to toggle between .h and .m?

Answer 1

Apple changed all sorts of shortcuts, but to switch between header and implementation, the new shortcut is,

⌃ + ⌘ + ↑/↓

You can change it back to the previous ⌥ + ⌘ + ↑/↓ in Preferences > Key Bindings.

Look for the Jump to Next Counterpart and Jump to Previous Counterpart commands.

If you are working on a big screen, you could use the Assistant layout's split view, and have the .h and .m files side by side.
