menubar - Applescript to show Apple menu bar items -

i applescript newbie. want know applescript show apple menu bar items arbitrary application (but many bar should remain orginal application).

i tried following script, using finder kind of dummy app, did not work.

tell application "system events"     tell process "finder"         tell menu bar 1             click menu bar item "apple"         end tell     end tell end tell 

can help?

ps-1: want know because control-f2 move focus menu bar not work, reported in following link: https://apple.stackexchange.com/questions/12723/control-f2-move-focus-to-menu-bar-only-works-occasionally

ps-2: tried post image, not allowed.

process 1 frontmost true gets frontmost process:

tell application "system events" tell (process 1 frontmost true)     click menu bar item 1 of menu bar 1 end tell 

clicking menu bar items doesn't work in full screen windows though. , if system events not used few minutes, closes automatically, , there's short delay when it's opened again.
