Shortcut / Link / Trigger to menu action Copy

[Carina Björndahl]

I would like users to be able to click on a button/link on a page to trigger the "page copy-action" without choosing it from the menu. 

I want the copy dialog where you can choose space is shown when link/button is clicked. 

(I can fetch the action-url on the menu, but that only copies the document to the current space). 

Is there a simple way to achieve this?
