 Occasionally you will want to answer with raw text that should not be converted into a math expression. For example, if
 the answer is a word. For this kind of answer, you should enter "text mode". There is a "Tt" button on the palette  that

+
+### Navigating Math
+
+When focus is on a piece of math content, there is a small help icon in the upper right. Click this icon to see a guide
+for how to navigate inside the math content. This can help you understand the meaning of the math content. For example,
+here we have navigated to the piece of math content inside the radical:
+
+[!Highlighting the discriminant in the quadratic formula!]{'discriminant.png'}{600}
+
+### Subtitles for Math
 
 Also in the main menu, there is an "Accessibility" submenu. Accessibility is enabled by default, but you can also select
 "Show Subtitles" in the "Speech" submenu.  This allows you to see math content verbalized. To do this, place focus onto
-a math expression and hit [|enter|]*.
-* At first, the entire expression is highlighted and there will be a verbal rendering of the expression.  
-[!Speech string for the quadratic formula!]{'explorerfull.png'}{600}
-* Use the down arrow to navigate "down" into a smaller piece of the math expression.
-* Use the left/right arrows to navigate to similar pieces of the math expression.
-* At any time you can navigate back "up" to a larger part of the expression, or "down" into smaller pieces. For example,
-you can see a verbalization for just this part of the expression above:  
-[!Speech string for the radicand of the quadratic formula!]{'explorerpiece.png'}{600} 
-* Return to the MathJax menu, Accessibility submenu, to explore options for how this explorer tool works.

+Under "Speech" you will find options for MathSpeak and ClearSpeak rules. The default is to use "MathSpeak verbose"
 rules, which try try to read math "literally" without context. For example, it reads [`(1,3)`] as "left parenthesis 1

+### Disabling Tab Indexing
