<p class="noindent">When you are reading a document in the preview
window and see something to change, it is convenient to go
immediately to the corresponding place in the source. To do so,
hold down <span class="keystroke">Ctrl</span> (Mac OS X:
<span class="keystroke"><img src="images/images/MacCmdKey.png" alt=
"PIC" /></span>) and click at the appropriate place in the preview;
the cursor will move and highlight the corresponding location in
the source window. The same is true in the other direction:
<span class="keystroke">Ctrl</span><img src="images/images/LMB.png"
alt="PIC" width="12" height="13" /> in the source will highlight
the same line in the preview window.<span class=

<div class="OSspecific">
<div class="OSspecificLogo OSWindows"></div>Here a remark for users
under Windows: this only works if <b>all</b> the names for

example, your document is in <tt>C:\Documents and

<h3 class="sectionHead"><span class="titlemark">5.2</span> <a id=
"x30-320005.2" name="x30-320005.2"></a>Special comment strings</h3>
<!--l. 20-->
<p class="noindent">Special comments, at the very beginning of the
files, can be used to manage two other aspects of the compilation. 
<!--l. 22--></p>
<p class="indent">By default, T<sub>E</sub>Xworks uses the “utf-8”
encoding<a id="dx30-32001" name="dx30-32001"></a> for loading and
saving files, but some files could be saved in another encoding.
Common ones are “latin1”<a id="dx30-32002" name="dx30-32002"></a>,
which is the dominant encoding on Windows when using western
languages, and “Apple Roman” which is dominant on Mac OS. 
<!--l. 24--></p>
<p class="indent">To set a different encoding<a id="dx30-32003"
name="dx30-32003"></a> for a specific file one can put the
following at the beginning of that file:<a id="dx30-32004" name=
"dx30-32004"></a></p>
<div class="fancyvrb" id="fancyvrb10">
<a id="x30-32006r1" name="x30-32006r1"></a><span class=
"ec-lmtt-10x-x-109">%</span><span class=
"ec-lmtt-10x-x-109">&nbsp;!TeX</span><span class=
"ec-lmtt-10x-x-109">&nbsp;encoding</span><span class=
"ec-lmtt-10x-x-109">&nbsp;=</span><span class=
"ec-lmtt-10x-x-109">&nbsp;latin1</span>
</div><!--l. 29-->
<p class="indent">Note that without this line, you must tell
T<sub>E</sub>Xworks the correct encoding manually. Otherwise, your
data could be corrupted! To override T<sub>E</sub>Xworks’s default
choice of encoding, use the menu that appears when you click on the
editor window’s middle status bar widget. <!--l. 31--></p>
<p class="indent">If you opened a file in T<sub>E</sub>Xworks that
was not saved as utf-8 but is lacking the <span class=
"obeylines-h verb"><span class="ec-lmtt-12">%</span><span class=
"ec-lmtt-12">&nbsp;!TeX</span><span class=
"ec-lmtt-12">&nbsp;encoding</span></span> line, it might be
displayed with (some) weird characters<a id="dx30-32007" name=
"dx30-32007"></a>. In that case, you can specify the correct
encoding via the status bar widget menu in the same way, but it is
<em>imperative</em> that you then use <em class="c10">Reload using
selected encoding</em> from the same menu! This forces
T<sub>E</sub>Xworks to open the document again with the encoding
you selected, the weird characters should be replaced by normal
ones, and only then it is safe to continue to work normally. To
avoid having to repeat this procedure each time you open this file,
you should either switch to utf-8 for saving it in the future or
add a proper <span class="obeylines-h verb"><span class=
"ec-lmtt-12">%</span><span class=
"ec-lmtt-12">&nbsp;!TeX</span><span class=
"ec-lmtt-12">&nbsp;encoding</span></span> line. <!--l. 33--></p>
<p class="indent">If we want to compile a file with another
programme<a id="dx30-32008" name="dx30-32008"></a> than the default
TE X or L<span class="ec-lmr-8">A</span>TE X, we put at the
beginning of the file: <a id="dx30-32009" name=
"dx30-32009"></a></p>
<div class="fancyvrb" id="fancyvrb11">
<a id="x30-32011r1" name="x30-32011r1"></a><span class=

</div><!--l. 38-->
<p class="noindent">for example:</p>
<div class="fancyvrb" id="fancyvrb12">
<a id="x30-32013r1" name="x30-32013r1"></a><span class=

"ec-lmtt-10x-x-109">&nbsp;=</span><span class=
"ec-lmtt-10x-x-109">&nbsp;xelatex</span>
</div><!--l. 43-->
<p class="indent">Pay attention to this last instruction. You have
to use the name of the programme here which should be used for the
whole project, as the first encountered programme when starting
typesetting is used (which is the one from the sub-document you are
in). T<sub>E</sub>Xworks will use that programme, even if another
name appears in the main document! <!--l. 45--></p>
<p class="indent">When opening a document which contains a
<span class="obeylines-h verb"><span class=
"ec-lmtt-12">%</span><span class=
"ec-lmtt-12">&nbsp;!TeX</span><span class=
"ec-lmtt-12">&nbsp;program</span></span> line, the specified
programme will become the one to use and its name will appear in
the drop down menu in the toolbar; you can, however, override this
by selecting a different one from the drop down list, if you want. 
<!--l. 49--></p>
<p class="indent">In addition, you can set the spell checking
language by a similar comment line: <a id="dx30-32014" name=
"dx30-32014"></a></p>
<div class="fancyvrb" id="fancyvrb13">

<p class="noindent">The language codes available on your system are
listed in parentheses in <em class="c10">Edit</em> <span class=

can specify the width of the lines; you can also re-format lines
which have already been split.</p>
<h3 class="sectionHead"><span class="titlemark">5.4</span> <a id=

<p class="noindent">When a document is becoming long and you want
to move to a specific place (a chapter, a section, a subsection,
…)<a id="dx30-34001" name="dx30-34001"></a> you normally need to
scroll the editing window to find the desired location, or use the
Find dialog if you remember a keyword in the chapter’s title. 
<!--l. 88--></p>
<p class="indent">To the same end, though a lot more comfortable,
you can also use the structural information in the document to
navigate the source: the menu item <em class=
"c10">Window</em><span class="lmsy-10x-x-120">→</span><em class=
"c10">Show</em><span class="lmsy-10x-x-120">→</span><em class=
"c10">Tags</em> opens a panel showing the information detected by
T<sub>E</sub>Xworks. Clicking on an item in the panel moves the
cursor to the corresponding part in the source. That panel, like
any other, can be resized by dragging its border. <!--l. 90--></p>
<p class="indent">The same action is possible in the PDF window
from <em class="c10">Window</em><span class=
"lmsy-10x-x-120">→</span><em class="c10">Show</em><span class=
"lmsy-10x-x-120">→</span><em class="c10">Table of
contents</em><a id="dx30-34002" name="dx30-34002"></a>, but this
only works if one has created structure tags in the PDF file using
the package <span class=

<h3 class="sectionHead"><span class="titlemark">5.5</span> <a id=
"x30-350005.5" name="x30-350005.5"></a>Organising the windows</h3>
<!--l. 94-->
<p class="noindent">By default, the editor/source window opens on
the left and the preview one on the right (when the corresponding
PDF file exists), thus splitting the screen in two. 
<!--l. 96--></p>
<p class="indent">You can change the position of the windows in the
<em class="c10">Window</em> menu. <span class=
"lmsy-10x-x-120">→</span><em class="c10">Stack</em> and
<span class="lmsy-10x-x-120">→</span><em class="c10">Side by
side</em> give the default effect if there is only one document
open. If not, <span class="lmsy-10x-x-120">→</span><em class=
"c10">Stack</em> creates a mosaic with all the windows. The other
options allow to place the windows for your convenience. It is also
always possible to resize and move the windows manually, of course.
<!--l. 98--></p>
<p class="indent">For the preview you can change the way it is
presented and of course the zoom<a id="dx30-35001" name=
"dx30-35001"></a> by <em class="c10">View</em><span class=

width</em> and <span class="lmsy-10x-x-120">→</span><em class=
"c10">Fit to window</em>; you can also zoom in and out. Shortcuts
exist for all these actions and are shown next to the menu items.

<h3 class="sectionHead"><span class="titlemark">5.6</span> <a id=

folder</h3><a id="dx30-36001" name="dx30-36001"></a> <!--l. 103-->
<p class="noindent">Very soon when one uses
(L<sup>A</sup>)T<sub>E</sub>X, one discovers that the working
folder is cluttered by many files which have the name of the source
file but different extensions: <span class="path">.aux</span>,
<span class="path">.log</span>, <span class="path">.toc</span>,
<span class="path">.lof</span>, <span class="path">.lot</span>,
<span class="path">.bbl</span>, … <!--l. 105--></p>
<p class="indent">All these are files needed by
(L<sup>A</sup>)T<sub>E</sub>X to be able to create the table of
contents, lists of figures/tables, the bibliography, the cross
references and, also very importantly, to keep track of what it did
(in the <span class="path">.log</span> file).</p>
