MathPlayer Navigation Commands in Word

To start navigation:

  • In NVDA, press NVDA+Alt+M. (The NVDA key is Insert. Caps Lock can also be enabled as an NVDA key.)
  • In Window-Eyes, press Ctrl+Shift+A.

To exit navigation:

  • In NVDA, press Esc.
  • In Window-Eyes, press Ctrl+Shift+A.

Navigation modes

There are two navigation modes, each of which can be set:

  • Speech after move mode: Whether the expression is read or described (a summary/outline) after each move.
  • Navigation mode: Navigate by subexpression, small piece, or character (shift+down/up arrow will cycle to smaller/larger modes and then wrap around). See next section for explanations of these modes.

Navigation Modes

  • Enhanced mode: Navigation is by mathematically meaningful pieces (operators, delimiters, and operands).
  • Simple mode: 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 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.
  • Character mode: This is actually two useful modes -- word mode and character mode (zoom in to get "real" character mode). Moves by words/characters. This differs for numbers of more than one digit and function names such as "sin" that are multiple characters. Otherwise, word and character navigation is the same.

Typical Use

Typically, you begin navigating by zooming in (down arrow) one or more levels, and then moving right (right arrow) as desired. Some larger expressions require zooming in again as you move to the right.

Backspace will take you back to where you were, which is not always the same as moving to the left. For example, if right arrow moved you out of a fraction, backspace will take you back to where you were in the denominator and left arrow will land on the entire fraction.
