Covering vs.

\end_layout

\end_inset


\end_layout

\begin_layout Frame
The difference between 
\begin_inset Quotes eld
\end_inset

covering
\begin_inset Quotes erd
\end_inset

 and 
\begin_inset Quotes eld
\end_inset

hiding
\begin_inset Quotes erd
\end_inset

 is that hidden content is treated as if it isn't there,
 while covered content is just covered (and the space is reserved).
 If we would have hidden the quote on the last slide and not covered,
 it would only have taken space on appearance:
