Scripting App Store

tell application “System Events” to click menu item “App Store…” of menu 1 of menu bar item “Apple” of menu bar 1 of application process “Finder”

Now: How to click row 8 (Updates) ?

If I undertand you…

tell application "System Events" to tell application process "App Store"
	set frontmost to true
	tell menu bar 1
		tell menu bar item "Store"
			tell menu 1
				click menu item "Updates"
			end tell
		end tell
	end tell
end tell

Thanks Frederik - how could I have overseen that …
