Prevent Common Integration Pitfalls
Make activation discoverable
Practice: Provide a visible, keyboard-operable explanation or control for the on/off command, mode commands, label selection, and exits. Communicate the current state programmatically.
Watch for: Users have no visible way to discover OpenKeyNav or determine whether its command layer is active.
Verify complete target coverage
Practice: Inventory complete processes and test every relevant state. Pay particular attention to listener-only actions, covered or offscreen targets, Shadow DOM, cross-origin frames, composite widgets, and dynamic content.
Watch for: A successful Click Mode demonstration is treated as coverage of every application function.
Pair visible labels with accessibility semantics
Practice: Supply programmatic names, roles, values, states, descriptions, and relationships through the host page. OpenKeyNav labels communicate which characters select a target.
Watch for: Generated target labels are expected to communicate the target's purpose to assistive technologies.
Complete each movement workflow
Practice: Configure and test the complete movement workflow. Announce selection, errors, cancellation, and completion, then place focus where the user can continue.
Watch for: Sources and destinations are configured while cancellation, invalid routes, state updates, feedback, or focus remain undefined.
Resolve shortcut conflicts
Practice: Test the final key map across supported input methods and technologies. Keep the persistent off mechanism discoverable.
Watch for: OpenKeyNav commands collide with text entry, host shortcuts, browser commands, operating-system commands, screen readers, or speech input.
Use diagnostics as focused review
Practice: Use the diagnostic heuristic to identify actions for focused review of semantics, focus, activation, and task completion. Pair the result with complete workflow evaluation.
Watch for: A marked candidate is treated as a conformance verdict, or zero candidates are treated as proof of accessibility.
Keep focus useful
Practice: Verify visible, meaningful focus after direct activation, navigation, route changes, dialogs, errors, cancellation, and movement completion.
Watch for: A selected action completes while focus becomes hidden, detached, or unrelated to the next task step.
Test complete states and outcomes
Practice: Cover responsive layouts, asynchronous updates, validation errors, permissions, empty states, long content, dialogs, cancellation, and supported browser and assistive-technology combinations. Include disabled keyboard users in task-based evaluation.
Watch for: Testing stops after one viewport and one successful interaction.
