Xcode line duplication (without overwriting your clipboard)

I find this shortcut extremely useful in Xcode: duplicate one or several lines without losing what you have on the clipboard.

Bind keys to duplicate lines in Xcode

1. To add custom key bindings in Xcode, you have to edit this file (su privileges required): /Applications/Xcode.app/Contents/Frameworks/IDEKit.framework/Versions/Current/Resources/IDETextKeyBindingSet.plist

			throw StripeWebhookError.missingSignatureHeader
