+\section{Pausing Sage\TeX}
+\label{sec:pausing-sagetex}
+
+Sometimes you want to ``pause'' for a bit while writing your document if
+you have embedded a long calculation or just want to concentrate on the
+\LaTeX{} and ignore any Sage stuff. You can use the \verb|\sagetexpause|
+and \verb|\sagetexunpause| macros to do that.
+
+\sagetexpause
+
+A calculation: $\sage{factor(2^325 + 1)}$ and a code environment that
+simulates a time-consuming calculation. While paused, this will get
+skipped over.
+\begin{sageblock}
+  import time
+  time.sleep(15)
+\end{sageblock}
+
+Graphics are also skipped: \sageplot{plot(2*sin(x^2) + x^2, (x, 0, 5))}
+
+\sagetexunpause
+
 \section{Make Sage write your \LaTeX{} for you}
 
 With \textsf{Sage\TeX}, you can not only have Sage do your math for you,
Tip: Filter by directory path e.g. /media app.js to search for public/media/app.js.
Tip: Use camelCasing e.g. ProjME to search for ProjectModifiedEvent.java.
Tip: Filter by extension type e.g. /repo .js to search for all .js files in the /repo directory.
Tip: Separate your search with spaces e.g. /ssh pom.xml to search for src/ssh/pom.xml.
Tip: Use ↑ and ↓ arrow keys to navigate and return to view the file.
Tip: You can also navigate files with Ctrl+j (next) and Ctrl+k (previous) and view the file with Ctrl+o.
Tip: You can also navigate files with Alt+j (next) and Alt+k (previous) and view the file with Alt+o.
