Add a custom external program link to the "Edit using" submenu
Sometime the Edit mode of Acrobat is useful to extract vectorial graphics from a page. Once selected the elements in the page you do a right click and the last item on the context menu is "Edit using".
Depending on the selection the submenu will propose "Microsoft Paint" for raster images or Acrobat for graphic elements. Other that this choice on the submenu there is "Open with..." that let you select an executable file to which pass as a parameter the path of a temporary PDF document that contains only the selection.
It will be useful to have more than a external program link in the submenu, it will save several clicks to reach the external program throug the "Open with..." option every time, especially when you have to do it hundreds of times on a document.

I found a workaround playing on the registry key
