Differential Simulator accessibility

The simulator provides keyboard controls, screen-reader status updates, support for browser magnification and large text, and reduced motion.

Keyboard operation

Keyboard operation reaches every action. Direct differential-counter keys work from the top number row and numeric keypad. Every image display action also has a page control.

Text status

The visible status line and screen-reader announcements report the same current cell, WBC count, correction, image state, and result.
