Some beamer color themes (as seagull) define alert text as bold font.
However, sold font alerts are annoying when one uses overlay (eg:
\onslide+<2->), because bold text takes more space than normal text, which breaks the illusion of an animation.
To change alert from normal to bold, we can use the command
(see here). Unfortunately, I was unable to revert this by using something like
I don't know if this is because this command is wrong or if it is because it can't override seagull's settings.
Does someone know a trick to set non-bold text with the
\alert command while using seagull color theme?
