<title>Search with SyncTeX</title>
<p>
   After you <link xref="synctex-compile">compile your TeX file with SyncTeX</link>, you will be able to search.  SyncTeX even supports forward and backward search from an included file.
</p>

<section id="forward-search">
    <title>Forward search: from TeX to PDF (from <app>gedit</app> to the <app>document viewer</app>)</title>
     <p>
     Forward search allows you to click on a specific section of TeX source code, and jump to the associated position in the PDF.  To perform forward search:
 </p>
<steps>
<item>
<p>
  Click on a line in the TeX file.
</p>
</item>
<item>
<p>
  In <app>gedit</app>, click <guiseq><gui>Tools</gui> <gui>Forward Search</gui></guiseq>. The corresponding line in the PDF will be outlined in red.
</p>
<p>
Alternatively, you can press <keyseq><key>Ctrl</key><key>Alt</key><key>F</key></keyseq>, or <keyseq><key>Ctrl</key>left click</keyseq>. The corresponding line in the PDF will be outlined in red.
</p>
</item>
</steps>
<note>
<p>
   If the corresponding PDF file is not open, performing a forward search will open the PDF in the <app>document viewer</app>.
</p>
</note>
<p>
 If you have a complex project with several TeX files you can put
</p>
<code>% mainfile: mainfile.tex</code>
<p>
either in the first or last three lines of each included TeX file, and forward search will work. Backward search should always work, even if you don't add the modeline.
</p>

</section>

<section id="backward-search">
    <title>Backward search: from PDF to TeX (from the <app>document viewer</app> to <app>gedit</app>)</title>
     <p>
 Backward search allows you to click on a specific line in the PDF file, and jump to the associated line in the TeX source code.
</p>
<p>
You can perform a backward search by pressing <keyseq><key>Ctrl</key>left click</keyseq> in the <app>document viewer</app>. The corresponding line in the TeX source code will be highlighted.
