Automator – Start Service Automatically After Opening an Application

This is weird, but I have seen at least three people on Apple Support Communities who had this problem when a of process "x" and a tell application "System Events" to are on the same line.

Try this.

on run {input, parameters}
  tell application "System Events"
      tell process "TextWrangler" to set visible to not visible
  end tell
end run

What is ⌃F9 meant to do? This worked for me when I wrapped it in a service:

tell application "System Events"
    key code 100 using control down -- ^F8
    delay 0.1
    key code 125 -- down
    key code 125
    keystroke return
end tell

You could try running the workflow with automator -v:

$ automator -v ~/Library/Services/lock.workflow/
Starting Automator…
Run AppleScript is running

Run AppleScript is finished

The Automator workflow has completed.

There are several issues with using Automator services to assign shortcuts to scripts though. See this question. If you run the service with a shortcut that has modifier keys, there might not be enough time to release them before the key code commands.

You could also use a script like this:

tell application "System Events" to tell process "SystemUIServer"
    tell (menu bar item 1 where description is "Keychain menu extra") of menu bar 1
        click
        click menu item 1 of menu 1
    end tell
end tell
