Open layout in existing window

Every new release it seems I have to ask this question. DOpus simply has way too much flexibility and after an hour of browsing the Help and experimenting every combination I can think of, I give up.

What do I set a custom button's command to, so that it simply switches the current window to a saved lister layout. I don't want a new window, I just want to set the left and right panes to the contents of a saved lister. I had a whole bunch of buttons created in DOpus 10, but they've all disappeared in DOpus 11 and so far I haven't been able to recreate a single one that works. The saved listers all exist, but right now they're useless to me.

HELP!

I know when I see the answer it will be a Duh! - forehead slapper, but right now I'm stuck.

Your old toolbars are still there after you upgrade (you should be shown a message telling you about this as you run the new version for the first time) so you can turn them back on and look for the buttons you had before.
