Accessibility / Screen Readers / NVDA Helper / NVDA Helper Popover Bookmarklet

The NVDA Helper Popover (minified) bookmarklet displays a quick reference guide for NVDA in a native HTML popover. Creates a green "NVDA Helper" button in the bottom-right corner that opens a compact popover with essential NVDA shortcuts including on/off, reading, navigation, headings, landmarks, tables, lists, and links. Uses the native popover API for modern browser support. Close with X button, clicking outside, or pressing Escape. Useful for quick reference during testing without taking up full screen space..
