[idvusers] launching ISL file from menu bar

Hi again,

I want to create an additional menu bar item or two for some ISL files.  I see 
how to do this, but the examples online show how to use action= to call a 
jython method or an "action".. I'm not familiar with <action>... do I have to 
use this to launch a specific ISL file from a menu item?  

Thanks,
Mike U
