In Beamer, I'm using \uncover because I want the omitted text to take up space. But I don't want the grayed-out default rendering. Is there a way to use \uncover, or an equivalent, that will take up the same space as the text but be completely invisible when rendered?

The default setting of beamer is invisible for uncovered text.


Hello World!

\uncover<2->{Example Text}

Maybe your scheme changes the default to transparent. You can set up the behavior by:


See section 17.6 “Transparency Effects” in the beamer manual for more details about the appearance of covered elements.
