Extending cut-and-paste: paste / pop-paste from anywhere within the list

Similiarly to being able to cut/copy items into any position within the list, the user could paste from any position within the list.

For example, pasting from the last position in the list

     CTRL(+SHIFT)+V

that is, ordinary paste.

or pasting from the second item in the list:

     CTRL(+SHIFT)+V,2

Those paste operations would leave the pasted item on the clipboard.

A 'pop-paste' would remove the pasted item from the clipboard. You could pop-paste the last item on the clipboard

     CTRL(+SHIFT)+V,-

If there were four items on the clipboard and you pop-pasted the second item

     CTRL(+SHIFT)+V,2,-

then the items that were originally at the third and fourth positions would be shifted one position to the left, into the second and third positions.
