for disjunction, simply add two identical actions, one with cond=appOnTop("first-place-it-should-work") and one with cond=appOnTop("second-place-it-should-work") i forget what the 'desktop' screen is called {you want the title property of the window for it}. beware! what you want is probably not possible, because the default action {i.e. changing the volume} WILL happen no matter what other actions you do. im working on this, not sure its possible yet.
