Easiest way to get path of currently-opened file in Adobe Acrobat? When viewing a file in Adobe Acrobat Pro XI on OSX Yosemite, I sometimes want to send the file to another application. To create an action in KeyboardMaestro, I need to get the path of the currently-open file from Acrobat. How can I get the path? 

A way to send the value to the clipboard would be enough; getting a value I can manipulate in AppleScript would be even better.
So here's an AppleScript that I pasted together with the help of some other answers and the AppleScript reference. This puts the URL of the frontmost Acrobat document to the clipboard, e.g:
file://localhost/Users/Your%20Username/Documents/Some%20Folder/Filename.pdf

 tell application "System Events"
        tell process "Acrobat"
            set thefile to value of attribute "AXDocument" of window 1
        end tell
    end tell
 set the clipboard to thefile
