Accessibility / Analysis / Keyboard Unit Tester Bookmarklet

The Keyboard Behavior Unit Tester bookmarklet automatically tests whether interactive controls respond to keyboard activation. Finds links, buttons, and inputs, programmatically dispatches Enter and Space keyboard events, measures if click handlers were triggered, and reports elements that failed to respond to keyboard activation. Helps identify interactive elements that only work with mouse/touch input, which is a WCAG violation. Displays an alert with the count of silent (non-responsive) elements.
