Add line transpose shortcut?

Hey guys,

One feature I loved in Notepad++ was the "line transpose" shortcut (CTRL+T). It would simply swap the line you're current on with the above line. This is extremely useful for re-ording lists of items in HTML or ordering CSS stylings in alphabetical order.

Does PHPStorm currently have a shortcut that does this? If not would you please include it in an upcoming patch :)?

Many thanks

David
