is there a keystroke to hide only one open window of firefox or textedit for example? or to only bring one to the front? often I want only one window while referencing another program, but if that window is under other open windows, i don't see a way to switch to JUST that window without other ones coming to the front and getting in the way of what i'm trying to reference. i could minimize the larger one, but I'd rather not have it cluttering up my dock. any suggestions? thanks!
