How to not show on client-list-combined-menu

[dcarroll]

OK, I was very proud of myself. I edited my rc.xml file to identify my 
email client and put it in precisely the right position on all 14 of my 
desktops.

How can I make it to NOT display on the client-list-combined-menu, 
(which is now 14 rows taller than I'd like)?

To no avail I played with the skip_panel and skip_pager options. Forgive 
the newby question, but I'm assuming the client-list menu is neither a 
pager, nor a panel. Right? Wrong? Missing the point entirely?

Sincerely,
