Accessing dock icon right-click menu items with AppleScript

Question

Is there any way to get an AppleScript to access the menu items that come up when you right click on a dock icon?

Specifically, here's what I want to do:

I use Google Chrome as my web browser on MacOS X Snow Leopard. I am a keyboard shortcut addict, and I use QuickSilver to create keyboard shortcuts for anything I can. One of the most common things that I do is to open a new web browser window. But I use Spaces frequently to partition my tasks that I am currently working on, and when I open a web browser or web page with a QuickSilver trigger, spaces switches to the last space that I used Chrome on and opens a new tab, which often distracts me for hours because it brings me to a different space and thus a different task. I can fix this by right-clicking on the Google Chrome icon and clicking the "New Window" option, which opens a new window on the current space. But in AppleScript, to do anything with Google Chrome, the first thing I have to do is activate it, which brings me back to the original problem! Can anyone think of a solution to this problem, AppleScript or otherwise? It has become a serious problem. Back when I used Firefox, I solved the problem by changing a preference item that says "Always open pop-up links in a new window" or something like that, which was kind of a sledge hammer approach, but it worked. I can always go back to Firefox, but I thought I'd ask my question here first. Anyone with any ideas?

Not sure if you are still interested but...

 tell application "Dock"
    activate
end tell
tell application "System Events"
    tell process "Dock"
        set frontmost to true
        activate
        tell list 1
            perform action "AXShowMenu" of UI element "Google Chrome"
            delay 1
            repeat 4 times -- count number of items to the one you want
                key code 126 -- up arrow
                -- key code 125 -- down arrow
            end repeat
            delay 1
            repeat 2 times
                key code 36 -- return key
            end repeat
        end tell
    end tell
end tell

For anyone who is interested, I think I've got a reasonable working solution to this problem, but it doesn't involve right-clicking on dock icons.

First, you have to uncheck "When switching to an application, switch to a space with open windows for the application" in the Spaces preference pane of System Preferences. Then I wrote the following AppleScript:

tell application "Google Chrome" to activate

tell application "System Events"
    tell process "Google Chrome"
        try
            set var to get name of window 1
        on error
            set var to "no window exists!!!"
        end try
    end tell
end tell

if var is "no window exists!!!" then
    tell application "System Events"
        tell process "Google Chrome"
            click menu item "New Window" of menu "File" of menu bar 1
        end tell
    end tell
else
    tell application "System Events"
        tell process "Google Chrome"
            click menu item "New Tab" of menu "File" of menu bar 1
        end tell
    end tell
end if

I launch this AppleScript using Spark, which allows me to assign a shortcut key to it.

It's a little bit slow, particularly when the system is under a load, but usually doesn't take longer than a second or so to run. It also avoids the problem I was having with Firefox, where I would end up with dozens of windows open at the end of the day.

As a variation to the most upvoted answer, here's a version of the script that accepts the name of the menu item, which lets you avoid having to do any counting.

This example clicks "Go to Folder..." from Finder's dock menu.

tell application "Dock"
    activate
end tell
tell application "System Events"
    tell process "Dock"
        set frontmost to true
        activate
        tell UI element "Finder" of list 1
            perform action "AXShowMenu"
            click menu item "Go to Folder…" of menu "Finder"
        end tell
    end tell
end tell

The Chromium nightly builds now contain AppleScript support, and this should make it into Chrome before long. It means you can now do:

tell application "Chromium"
    make new window
    activate
end tell
