Simple Creation of Footnotes in Word 2011

I’m sure this is VERY basic and I feel like an idiot asking, but I’ve just used Applescript for the first time today. I am trying to create a basic hotkey that will insert footnotes in Word 2011 using CTRL+F. Here’s what I’ve tried in Applescript:

tell application “System Events” to keystroke “f” using {command down, control down}
tell application “System Events” to key code 36

I’ve tried setting this script to run with the CTRL+F hotkey using Better Touch Tools keyboard shortcut option, and I’ve tried to run the script directly in Word 2011 by adding it to my Word Script Menu. In both cases the first line works fine (the footnote dialog box appears), but the “Return” key is not simulated. My guess is that somehow I need to tell the script to activate the footnotes dialog box before key code 36, but I have no clue how to do that.

Thanks for the help.

I figured out a way to do this with the Keyboard options in System Preferences, but I’m still interested in why my first go would not work as an applescript. Thanks.
