How do I generate a list of keyboard shortcuts for any given application

Question

I want to generate a list of keyboard shortcuts for all of the applications I have on my Mac. I want the list to be a simple text (or rtf) file that I can edit and organize. (By edit, I don't mean change the shortcuts, only the report of them.)
I was using Key Cue, but it does not let me save the list to a text file.
I want this for several purposes. One is to have a easy to reference list of shortcuts to learn. Another is to find unused key combinations that I can use for my own keyboard shortcuts that I create with DefaultKeyBinding.dict.
Note: The program doesn't have to an OS X app. A program that runs from a shell without a GUI is plenty adequate.
If there is a way to read the keyboard commands from a plist list or other such file, and any of you know the format for these or where I can find them, I can write a Perl script myself to do it.

Well, the info is stored in...
/Users/YourUserName/Library/Preferences/com.apple.universalaccess.plist
PlistPro has a way to convert it to ASCII, but you'll srtill have work to do, as...
