yes, you created a menu, now you need an event that calls that menu:
chanprint(cs->ctl, "daemenue window 1");

if you had a Control *button, called "button" you could asociate it with
something like:

chanprint(cs–>ctl, "button  format %q", "%q:   daemenu window 1");

I could be wrong, I haven't used control(2) in some time, but I think you'll get
the idea :)
