Emacs outline facility provides a powerful tool for browsing textual
material based on its implicit structure.
By default, command <span><b class="command">outline-minor-mode</b></span>
sets up Emacs to recognize lines beginning with
<tt class="literal">***</tt>
as header lines. This can be changed on a per buffer basis by setting
up Emacs variable <tt class="varname">outline-regexp</tt>
to a regular expression that matches header lines.
When using Emacs <span><b class="command">view-mode</b></span>
to read text, this feature is especially useful when combined with
Emacspeak built-in feature that loads a directory specific
file to customize Emacspeak on a per-directory basis.
Thus, one can organize electronic texts by placing files for a given
book in a specific directory, and then creating a file
called <tt class="literal">.espeak.el</tt>
in that directory that sets up things like Emacs variable
<tt class="varname">outline-regexp</tt>.

control additional status information that may
be spoken by this command. When possible, this
command uses tones, midi icons and auditory
icons to make the spoken feedback more succinct.
Here is a brief summary listing the various
items of status information conveyed by command
<span><b class="command">emacspeak-speak-mode-line</b></span>:
</p><table class="simplelist" border="0" summary="Simple list"><tr><td>Shell-mode The working directory is

<span><b class="command">emacspeak-toggle-which-function</b></span>,
the name of the function containing the cursor

</td></tr><tr><td> mail-alert Produces an

auditory tone when the
<span class="emphasis"><em>current</em></span> buffer is
<span class="emphasis"><em>read-only</em></span>.</td></tr><tr><td>

current buffer.</td></tr><tr><td> line-number

Current recursion level when <span class="emphasis"><em>recursive

enter <span class="emphasis"><em>recursive edit</em></span> in
Emacs in very few specialized
cases.</td></tr></table><p> Finally, note that
the feedback is designed using the principle
<span class="emphasis"><em>no news is good news</em></span>, thus,
in many cases the absence of a cue is itself a
cue. As an example, Emacspeak produces an
auditory tone only if a buffer is
<span class="emphasis"><em>read-only</em></span> --the absence of
the tone indicates the buffer can be editted
which is usually the case. Similarly, no tone
is produced when a buffer does not need saving.

Emacspeak allows you to configure your favorite
streams as an organized hierarchy. The Emacspeak
distribution comes with such a collection of
streams I listen to on a frequent basis. You can
access these by using standard Emacs completion
when prompted for a <tt class="computeroutput">RealAudio
Resource</tt> by command
<span><b class="command">emacspeak-realaudio</b></span>. </p></td></tr><tr class="question"><td align="left" valign="top"><a name="id2244377"></a><a name="id2244379"></a><b>5.9.</b></td><td align="left" valign="top"></td></tr><tr class="answer"><td align="left" valign="top"><b></b></td><td align="left" valign="top"><p>

There are a number of available options, none of which are completely
satisfactory.
Here is a summary of what is available.</p><div class="orderedlist"><ol type="1"><li><p>
<span><b class="command">W3</b></span>.
This is still my web browser of choice though it has sadly fallen by
the way-side in the last few years.
W3 lacks the features you need to interact with many commerce sites,
but is a very flexsible and powerful solution for
efficiently browsing content.
Emacspeak's web-specific wizards
make up for many of the short-comings encountered when navigating
complex web sites and these wizards work best with
the W3 browser.
Emacs command: <span><b class="command">w3</b></span>.
</p></li><li><p>
<span><b class="command">Emacs W3M</b></span>
This is a light-weight browser compared to W3 and provides an Emacs
interface to the underlying
W3M browser.
It is a good solution for browsing content --especially on slow
machines.
Emacs command: <span><b class="command">w3m</b></span>.</p></li><li><p>
<span><b class="command">Lynx</b></span>.
The oldest terminal based browser of them all.
It's still a good solution for some interactive sites, but its lack of
support for tables can make some sites very confusing.
Emacspeak command: <span><b class="command">emacspeak-lynx</b></span>.</p></li><li><p><span><b class="command">Links</b></span>.
This is <span class="emphasis"><em>Links</em></span> with an <span class="emphasis"><em>i</em></span> and
not to be confused with the older Lynx browser.
It has rudimentary Javascript support and is under active development.
Emacspeak command: <span><b class="command">emacspeak-links</b></span>.</p></li><li><p>
<span><b class="command">IBM HPR</b></span>
IBM Home Page Reader is a speech extension for Internet Explorer that
can be run under VMWare.
I use this as a last resort solution if I must interact with
Javascript heavy sites.</p><p>For this, you need to have VMWare installed and
configured.
I run Emacspeak under the Sawfish window manager on Linux, and bring
up Win98 by typing <span><b class="command">win98</b></span>
inside an Emacs shell buffer. </p><div class="epigraph"><p>
