Copy editor changes to the clipboard so when I'm done I can just paste result into program, like Snipping Tool is/was

When I am making annotations in the Editor, I want those changes to be continuously copied to the clipboard, so that I can at any time stop making changes and paste the result into another window.

That is how Windows Snipping Tool worked and the Snip and Sketch.... It was so handy, but I do really like Greenshot and continue to use it even though I have to continually remember to hit "copy to clipboard" after I make my changes.
