[JW Lua] get all items of "Expression Tool"

[Jan Angermüller]

Hi Robert,

you should use the JW Lua class browser, the online class documentation 
and the examples that Jari put on his website to find this out.

The online class documentation starts here:
http://www.finaletips.nu/frameworkref/annotated.html
So you browse to FCTextExpressionDef and search for "Description" and 
you will have your solution.

The same result can be found in the JW Lua class browser:
Go to FCTextExpressionDef and enter "Description" in the Properties 
and/or Methods search fields. Then you'll even get a sample code.

Best,
Jan
