Of cause you can use+TAB to switch. But you cannot switch between different window of one app by that way.
Does anybody know some method to solve that? I just want switch window by only one click and by only my right hand.
I don't know what you have against using your left hand, especially since you use your left to
+TAB, but I think you totally skipped over this suggestion:+` switches between the different windows of an open application. This doesn't work if the windows are minimized, however (I wasn't exactly sure what you were saying about wanting minimized windows minimized so you could switch to them?) but if you have Leopard, you can give, say, Microsoft Messenger it's own space and let those windows totally consume the space, then switch to the space when you get a new message by +TAB to MSN and then +` to the message.
