I was able to cobble together something that works by modifying a snippet of code I found on the Internet.
I don't think it does anything harmful to iTunes, your Mac or the space time continuum but use at your own risk. It has had limited testing
1. Launch Script Editor (you can find it using Spotlight). It should open with a new blank document,
2. Paste the following code into the new document
Code:
tell application "System Events"
tell process "Finder"
option key down
tell application "iTunes" to activate
tell application "System Events"
tell process "Finder"
option key up
end tell
end tell
end tell
end tell
3. Click the "hammer" icon at the top of the Script Editor Window to compile and check for errors.
4. Choose Save to save the script somewhere you'll remember. In the File Format drop down choose "Application"
This script probably needs for you to have an AppleScript feature called access for Assistive Devices enabled. How you enable that varies depending upon which version of OS X you are using. You can find that information
here. You'll only need to do that once.
You could make an alias of this "application" for ease of use.
