<h1>Folding</h1>
|
||
|
|
<p>Notepad++
|
||
|
|
supports so called folding for your text documents. This means that
|
||
|
|
certain lines of your text can be hidden based on certain traits.
|
||
|
|
This works well for structured languages such as C++ or XML . Blocks
|
||
|
|
of texts are 'parented' to others and by folding them (also called
|
||
|
|
collapsing) only the first line is visible. This works well if you
|
||
|
|
want a quick glance at your document and skim for a relevant
|
||
|
|
position. Unfolding the text (a.k.a. Expanding or Uncollapsing) shows the text again.
|
||
|
|
<p>
|
||
|
|
You can recognize text that can be folded by looking at the fold
|
||
|
|
margin on the left. This margin shows icons and line to indicate the
|
||
|
|
structure of the text (the appearance of the margin can be changed,
|
||
|
|
see <a href="Styler%20Configurator.html#Fold">Styler Configurator</a> and <a href="Preferences.html#Edit_Components">Preferences</a>).
|
||
|
|
The current lexer determines the structure (see <a href="Languages.html">Languages</a>). By
|
||
|
|
default, the fold margin shows boxes and lines to indicate the
|
||
|
|
structure. A box with a minus sign (<img style="width: 12px; height: 16px;" alt="" src="Images/fold_min.png">) indicates the text can be
|
||
|
|
collapsed. Inversely, a box with a plus sign (<img style="width: 12px; height: 16px;" alt="" src="Images/fold_plus.png">) indicates the text
|
||
|
|
can be expanded. Folded text is additionally indicated with a
|
||
|
|
horizontal line where the text is collapsed. The first line of the
|
||
|
|
collapsed text will always remain visible. Lines on the fold margin
|
||
|
|
indicate that the textlines they run by are foldable. Vertical lines
|
||
|
|
(<img style="width: 8px; height: 14px;" alt="" src="Images/fold_line.png">) indicate multiple lines that can be folded together as a group,
|
||
|
|
which is terminated with a small horizontal line(<img style="width: 9px; height: 15px;" alt="" src="Images/fold_bar.png">) or a box.
|
||
|
|
<p>There
|
||
|
|
are multiple ways to <span style="font-weight: bold;">fold</span> text.
|
||
|
|
<p ><ul><li><font face="Times New Roman, serif">The
|
||
|
|
foremost means is by clicking with the <span class="shortcut">left mouse button</span> on a box
|
||
|
|
with a minus sign. This will simply collapse all the text that is in
|
||
|
|
this group.</font>
|
||
|
|
</li><li><font face="Times New Roman, serif">The
|
||
|
|
same procedure but with the <span class="shortcut">Ctrl</span> key pressed down will cause the
|
||
|
|
group to collapse, but also any sub groups inside. This effectively
|
||
|
|
means that if you were to unfold just that group, all subgroups would
|
||
|
|
still be folded.</font>
|
||
|
|
</li><li><font face="Times New Roman, serif">Using
|
||
|
|
the menu:<br></font><font face="Times New Roman, serif"><span class="menu_item">View->Fold
|
||
|
|
All</span> will fold every single group in the document, causing the minimal
|
||
|
|
amount of text visible.</font>
|
||
|
|
<span class="menu_item">View->Collapse
|

|
|
current level</span> will only collapse the current group (that is, the
|
||
|
|
group that contains the current line, anywhere in the group). This
|
||
|
|
will not collapse any subgroups.</font>
|
||
|
|
<span class="menu_item">View->Collapse
|
||
|
|
level...</span> will collapse the selected level (ranging from 1 to 8).
|
||
|
|
This will collapse all the groups on a particular level, but not any
|
||
|
|
subgroups. You can use this to view your text with a certain 'level
|
||
|
|
of detail'.</font>
