?: How to launch specific lister via MacroExpress

Hello Opus gurus,
I would like to launch a specific Opus lister when a specific program window opens. I am using MacroExpress to watch for the window trigger. Anyone know the command line to make this happen? Thanks so much,

A quick search of the forums found this. That shows you how to launch a specific lister layout from the command line.

Thanks so much, Steve. I'll give it a try. I guess I need to work on my search skills. Mine came up empty.
