Keystroke commands for open recent I want to set a keystroke command (Mountain Lion) to trigger the common File menu's Open Recent option.

I've tried the System Preferences => Application Shortcuts => Keyboard Shortcuts. My shortcuts show up in the applications' File => Open Recent menu, and when I type my assigned keystrokes there's a little flash in the File menu bar, but nothing else happens. 

Any ideas, y'all?
I have used FastScripts to assign a shortcut to this script:

tell application "System Events" to tell (process 1 where it is frontmost)
    tell menu bar item 3 of menu bar 1
        click
        repeat with x in {"Open Recent", "Open Recent File", "Recent Projects", "Open With"}
            if exists menu item x of menu 1 then
                click menu item x of menu 1
                exit repeat
            end if
        end repeat
    end tell
end tell


It opens an Open With menu in Finder and a menu for recent files in other applications.

There are other ways to assign a shortcut to a script using Quicksilver, Alfred, etc.
