Xcode "move line" keyboard shortcut

In Xcode 4, I have been sucessfully able to add new custom keyboard shortcuts to move lines around or to duplicate a line:

/Applications/Xcode.app/Contents/Frameworks/IDEKit.framework/Resources/IDETextKeyBindingSet.plist

<key>My Custom Keys</key>
<dict>
    <key>Move Line Up</key>
    <string>selectLine:, cut:, moveUp:, moveToBeginningOfLine:, paste:, moveUp:</string>
    <key>Move Line Down</key>
    <string>selectLine:, cut:, moveDown:, moveToBeginningOfLine:, paste:, moveUp:</string>
    <key>Duplicate Line</key>
    <string>moveToBeginningOfLine:, deleteToEndOfLine:, yank:, insertNewline:, moveToBeginningOfLine:, yank:</string>
    <key>Delete Line</key>
    <string>selectLine:, delete:</string>
</dict>

But the Move Line Up/Down uses copy/paste, which I would like to avoid. Anyone knows how to move lines with yank, just like the Duplicate Line I found there: Xcode duplicate line

Copied from https://stackoverflow.com/a/9078952/852828 as that isn't the accepted answer to the linked duplicate.

Xcode 4 has a new set of command for moving the line where the cursor is or the selected text with command + option + [ or ]

⌥⌘[ or ⌥⌘]

How to move lines in Xcode via the menu OR hotkeys:

If you are using a Windows keyboard, the commands would translate to:

• ⌥⌘[ ..... Alt + Win + [
• ⌥⌘] ..... Alt + Win + ]
