Copy/cut and paste playlist items with standard keyboard shortcuts

Again, I'm a heavy keyboard user and I would like to be able to manipulate the playlist entirely by keyboard. I would find it very convenient to be able to select playlist items using the arrow keys and shift key and than paste them where the selection is, instead of having to use the mouse to drag 'n' drop. I think it can make the process much faster and more precise, i.e. the user won't have to deal with exact aiming with the mouse.

My suggestion therefore is to add the ability to copy/cut and paste playlist item with the standard keyboard shortcuts. When a single playlist item is selected before pasting, the pasted item(s) should be placed above that selected item. When multiple playlist items are selected before pasting, the pasted item(s) should replace those items.
