Multiple-line cursor movements in XCode 4

Question

The same question has been asked for Xcode 3 But the solution there is said to not work with Xcode4. And no new solution is available there.

How to get a key-binding to move the curser up/down about 10 lines in Xcode 4 ?

Answer 1

Eureka! Inspired by the answer on line duplication, this is how you empower Xcode 4 with multiple-line movement:

1. Go to the folder /Applications/Xcode.app/Contents/Frameworks/IDEKit.framework/Versions/A/Resources
2. Open IDETextKeyBindingSet.plist.
3. Add a new dictionary Customized and two new command (say, Move Down 10 and Move Up 10) keys as the screenshot below:
4. Restart Xcode and go to Preferences - Key Bindings, search for your command.

5. Set a key combination for both commands:

6. Free at last from the shackles of the Jump To shortcut. Enjoy it!

Bonus: system-wide multiple-line movement

Unleash the cursor outside Xcode following with these steps:

1. Go to the folder ~/Library/KeyBindings
2. Open DefaultKeyBinding.dict.
3. Enter the following. Customize as appropriate.

   {

   "^~n" = ("moveUp:", "moveUp:", "moveUp:", "moveUp:", "moveUp:", "moveUp:", "moveUp:", "moveUp:", "moveUp:", "moveUp:");
   "^~p" = ("moveDown:", "moveDown:", "moveDown:", "moveDown:", "moveDown:", "moveDown:", "moveDown:", "moveDown:", "moveDown:", "moveDown:");

   }

4. Logout & Login

All of the above works on 10.8.2 with Xcode 4.5.1.
