<p class=MsoNormal>Title: The NVDA Method for Reading Mathematics in MS Word and
On the Web </p>
<p class=MsoNormal>Author: Louis Maher</p>
<p class=MsoNormal>Date: July 10, 2017</p>
<p class=MsoNormal> </p>
<p class=MsoNormal>Abstract: </p>
<p class=MsoNormal>I use Windows 10, NVDA 2017.2, Word 365 running locally, and
Firefox. MathPlayer 4 speaks, navigates, and brailles math with Nonvisual
Desktop Access (NVDA) in Microsoft Word & PowerPoint. MathType is
required for this capability. </p>

<p class=MsoNormal>I use Windows 10, NVDA 2017.2, Word 365 running locally, and
Firefox. MathPlayer 4 speaks, navigates, and brailles math with Nonvisual
Desktop Access (NVDA) in Microsoft Word & PowerPoint. MathType is
required for this capability. </p>
<p class=MsoNormal> </p>
<p class=MsoNormal>Here is a summary of the keyboard commands NVDA, combined
with Design Sciences MathPlayer, uses to read mathematics. </p>
<p class=MsoNormal> </p>
<p class=MsoNormal>In NVDA the command to turn the math navigation mode on or
off is: </p>
<p class=MsoNormal>NVDA plus Alt plus M. Remember that the NVDA key is Insert
or Caps Lock. If you toggle between the <b>Left Arrow</b> and <b>Right Arrow</b>
keys, the expression will be repeated. To exit math navigation, use the Escape
key. </p>
<p class=MsoNormal> </p>
<p class=MsoNormal>NVDA gives you a few helpful audio cues. For instance, when
you turn on navigation, NVDA will say “math”. If you try to turn on navigation
when you are not in a math expression, it will say “not math”. When you exit
navigation, it will say “out of math”. </p>
<p class=MsoNormal> </p>
<p class=MsoNormal>To zoom in, use the Down Arrow key while listening to the
expression when math navigation is on. To zoom back out, one level at a time,
use the Up-Arrow key. Zooming in does not change the visual</p>
<p class=MsoNormal>appearance (size) of the expression. </p>
<p class=MsoNormal> </p>
<p class=MsoNormal>Use the left and right arrows to hear the equation.</p>
<p class=MsoNormal> </p>
<p class=MsoNormal>In a document, when you first turn navigation on in a math
expression using the NVDA + Alt + M key combination, you will be in enhanced
mode. You can change the mode by pressing either </p>
<p class=MsoNormal>Shift + Up Arrow to change to character mode or Shift +
Down Arrow key to change to simple mode. Continuing to press Shift + Up Arrow
or Shift + Down Arrow will let you continue to cycle through the three
different modes. </p>
<p class=MsoNormal> </p>
<p class=MsoNormal>• Navigation mode to use when beginning to navigate an
equation:</p>
<p class=MsoNormal>list of 4 items nesting level 1</p>
<p class=MsoNormal>◦ Enhanced. Navigation is by mathematically meaningful
pieces (operators, delimiters, and operands).</p>
<p class=MsoNormal>◦ Simple. This moves by words except when you get to a
2D notation (fractions, roots, ...), then it speaks the entire notation.
Zooming in lets you explore</p>
<p class=MsoNormal>the 2D notation in the same mode. Zooming out or moving out
of the 2D notation brings you back to the outer/higher level of navigation.</p>
<p class=MsoNormal>◦ Character. This is two useful modes -- word mode and
character mode (zoom in to get "real" character mode). Moves by
words/characters. The two</p>
<p class=MsoNormal>modes differ when you are navigating numbers with more than
one digit and function names that are multiple characters. Otherwise, word and
character navigation</p>
<p class=MsoNormal>is the same.</p>
<p class=MsoNormal> </p>
<p class=MsoNormal>You can read (speak) or describe an expression without
toggling</p>
<p class=MsoNormal>the mode anytime by pressing the spacebar (read current) or
"Ctrl + Shift + spacebar" (describe current).</p>
<p class=MsoNormal> </p>
<p class=MsoNormal>In the math navigation mode, the "Where am I" command
is enter. The global "Where am I" command is control + enter.</p>
<p class=MsoNormal> </p>
<p class=MsoNormal><b>Shift + Enter will </b>reread your current location in
your current mode.</p>
<p class=MsoNormal> </p>
<p class=MsoNormal>When you wish to change from describe mode to read mode, or
from read mode to describe mode, make sure you are in an expression with
navigation turned on, then toggle between the modes by pressing <b>Shift + Spacebar</b>.</p>
<p class=MsoNormal> </p>
<p class=MsoNormal>A place marker is a remembered location inside an expression
that you can move to or have read. You can set as many as ten place markers while
you are navigating any expression. To clear all the place markers, you have set
in an expression, exit the expression and then return to it.</p>
<p class=MsoNormal> </p>
<p class=MsoNormal>Place markers are assigned numbers from 0 through 9. To <b>set</b>
a place marker at a location in an expression, go to that location, then press <b>Control</b>
plus the <b>number </b>you wish to assign to that location.</p>
<p class=MsoNormal> </p>
<p class=MsoNormal>After you have set a place marker in an expression, you can
jump back to the remembered location from anywhere in the expression by simply
pressing the number key for that place marker. After you press the number key,
you will hear the place marker announced and then you will hear the portion of
the expression that is at the marked location. </p>
<p class=MsoNormal> </p>
<p class=MsoNormal>You can hear a marked location in either read or describe
mode, without moving to the location, by pressing <b>Shift</b> plus the <b>number
</b>key (e.g., <b>Shift+1</b>) to have that portion <b>read</b> or by pressing <b>Control</b>
plus <b>Shift</b> plus the <b>number</b> key (e.g., <b>Control+Shift+1</b>)<b> </b>to
have that portion <b>described</b>. Then, if you want to be reminded of where
the marked portion fits in with the larger expression, use the <b>Where Am I"</b>
commands.</p>
