The structured text editor is represented by various editors that you can
use to edit files coded with markup tags:</p>

<p>You can access the structured text editor by right-clicking on a relevant
file name in Navigator or Package Explorer view and then clicking <uicontrol>Open
With</uicontrol> and selecting the editor mentioned above.</p>
<p>The structured text editor provides a consistent interface regardless of
the markup language with which it is associated. It provides capabilities
such as find and replace, undo, redo, a spelling checker, and coding assistance
(unless otherwise noted). It also highlights syntax in different colors. Following
is a brief description of some of the structured text editor's capabilities:</p>
<dl><dlentry>
<dt>syntax highlighting</dt>
<dd>Each keyword type and syntax type is highlighted differently, enabling
you to easily find a certain kind of keyword for editing. For example, in
HTML, element names, attribute names, attribute values, and comments have
different colors; in <tm tmclass="special" tmowner="Sun Microsystems, Inc."
tmtype="tm" trademark="JavaScript">JavaScript</tm>, function and variable
names, quoted text strings, and comments have different colors.</dd>
</dlentry><dlentry>
<dt>unlimited undo and redo</dt>
<dd>These options allow you to incrementally undo and redo every change made
to a file for the entire editing session. For text, changes are incremented
one character or set of selected characters at a time.</dd>
</dlentry><dlentry>
<dt>content assist</dt>
<dd>Content assist helps you to insert <tm tmclass="special" tmowner="Sun Microsystems, Inc."
tmtype="tm" trademark="JavaScript">JavaScript</tm> functions, HTML tags, or
other keywords. Choices available in the content assist list are based on
functions defined by the syntax of the language in which the file is coded.</dd>
</dlentry><dlentry>
<dt>user-defined templates and snippets</dt>
<dd>By using the Snippets view, you can access user-defined code snippets
and (for all code types except <tm tmclass="special" tmowner="Sun Microsystems, Inc."
tmtype="tm" trademark="JavaScript">JavaScript</tm>) templates to help you
quickly add regularly used text strings.</dd>
</dlentry><dlentry>
<dt>function selection</dt>
<dd>Based on the location of your cursor, the function or tag selection indicator
highlights the line numbers that include a function or tag in the vertical
ruler on the left area of the Source page.</dd>
</dlentry><dlentry>
<dt>pop-up menu options</dt>
<dd>These are the same editing options available in the workbench <uicontrol>Edit</uicontrol> menu.</dd>
