In Beamer, when you use \pause \uncover, or <+-> with itemize, the text that is covered is dimmed. But that could be distracting since people can still read ahead. Is there a way to disable this dimming?
On a similar note, it seems the amount of dimming depends on the level of nesting in a list, which can sometimes be even more frustrating since the next bullet separated by several sub-bullets becomes so much more prominent in the middle of the page. Can this be changed too?
I tried \only, but then the text jingles around since the layout thinks the text isn't there. I also tried different themes, but it doesn't seem to change the amount of dimming (of course, I could just be selecting bad themes).

beamermanual:\setbeamercovered{invisible}should be what you're after (by the way, this is the default setting). – diabonas Feb 24 '12 at 14:46
