"Paste As" command

Is there a "Paste as" command? Let's say I copy part of a screen with "print screen" if I paste it is a jpeg image, but with no name (only "clipboard"). Is there an option to paste and name the file as you paste it?

Clipboard

sorry, not specific enough

how do you get to the command editor?

There are extra % symbols in the document exampleimage

I've fixed those. Thanks.
