I'm running OS X Yosemite. ⌘-Delete deletes a whole line in every app. In some apps, it deletes a whole line and keeps deleting lines after that. In some, it deletes a whole line and stops, so I have to hit delete to move up to the previous line and then Command-Delete to delete a whole line again.
Is there a way to make it keep deleting lines in every app. The one I'm specifically talking about is Xcode.
