- function registerKeyHandlers () {
- const colorBox = $("#colorBoxContainer").dxColorBox("instance");
- colorBox.registerKeyHandler("backspace", function(e) {

- });

- // ...
- });

Screen Reader Support
The ColorBox component supports screen readers and complies to WAI-ARIA standards. The exceptions are listed in the Accessibility Standards Compliance topic.
To improve accessibility, use the inputAttr property to specify aria-label for the component. You do not need to specify aria-label
if you use label.
