Resolve Common Integration Issues

Use these checks to restore initialization, Click Mode labels, custom commands, dynamic-content discovery, and mode-entry performance.

Restore OpenKeyNav initialization​

Symptoms​

  • OpenKeyNav features are not working.
  • No labels are displayed when modes are activated.

Resolution​

  1. Load the browser build

    • Include the OpenKeyNav script in your HTML file.
    <script src="https://cdn.jsdelivr.net/npm/openkeynav/dist/openkeynav.umd.min.js"></script>

  2. Initialize after the document is ready

    • Initialize OpenKeyNav after the DOM content has loaded.
    document.addEventListener('DOMContentLoaded', () => {
        const openKeyNav = new OpenKeyNav();
        openKeyNav.init();
    });

  3. Enable the command layer

After the page loads, press Shift + O to turn OpenKeyNav on or off. OpenKeyNav keeps its character commands inactive until a user enables them. This persistent on/off mechanism supports the turn-off option in WCAG 2.1 Success Criterion 2.1.4: Character Key Shortcuts.

Restore Click Mode labels​

Symptoms​

  • Pressing the activation key does not show labels on clickable elements.

Resolution​

  1. Verify the target model

    • Confirm that each expected target is visible in the current document and viewport and represented by a native control, recognized interactive role, tabindex, editable state, or inline click handler.

  2. Use focused diagnostics during development

    • Keep focused keyboard diagnostics enabled while exercising Click Mode, then inspect outlined actions and direct-selection labels together with the target's semantics, focus, and activation result.
    const config = {
        debug: {
            keyboardAccessible: true
        }
    };
    const openKeyNav = new OpenKeyNav();
    openKeyNav.init(config);

Restore custom key bindings​

Symptoms​

  • Custom key bindings are not triggering the expected modes.

Resolution​

  1. Verify the command configuration

    • Confirm that the intended keys are passed during initialization.
    const config = {
        keys: {
            click: 'c',
            scroll: 'w'
        }
    };
    const openKeyNav = new OpenKeyNav();
    openKeyNav.init(config);

  2. Resolve command conflicts

    • Test the final keys with text entry, host-application shortcuts, browser and operating-system commands, screen readers, and speech input. Assign a different key where command ownership overlaps.

Profile slow mode entry​

Symptoms​

  • Slow performance when navigating or interacting with elements.

Resolution​

  1. Measure the complete mode-entry path

    • Use browser performance tools to profile target discovery, label creation and positioning, host-application event handlers, layout, and rendering.

  2. Test representative application states

    • Compare pages with many visible controls, large DOM updates, scrollable layouts, and repeated mode entry on supported production browsers and devices. Continue with Performance Optimization.

Include newly rendered elements​

Symptoms​

  • Dynamically added elements are not recognized by OpenKeyNav until the mode is re-entered.

Resolution​

  1. Complete the DOM update before mode entry
    • Add the elements, allow the application state to finish rendering, and then enter or re-enter the mode.
    document.getElementById('loadContentBtn').addEventListener('click', () => {
        setTimeout(() => {
            const newContent = `
                <div class="new-content">
                    <button>New Button 1</button>
                    <button>New Button 2</button>
                </div>
            `;
            document.getElementById('contentContainer').insertAdjacentHTML('beforeend', newContent);
            // OpenKeyNav discovers these buttons the next time the mode begins.
        }, 1000);
    });

Resolve conflicts with other page scripts or widgets​

Symptoms​

  • Another script or widget changes OpenKeyNav commands, focus behavior, labels, status, or cleanup.

Resolution​

  1. Isolate the interaction

    • Test OpenKeyNav with the other integration temporarily inactive, then restore integrations one at a time to identify the shared event, focus, or rendering behavior.

  2. Coordinate ownership

    • Compare shortcut handling, event propagation, focus movement, generated-element stacking, and cleanup. Configure non-conflicting commands and preserve each component's documented exits.

Verify the resolved integration​

After resolving an integration issue, repeat target-discovery, action-outcome, focus, shortcut, and complete-workflow tests in every supported environment. Share reproducible findings through the OpenKeyNav project.
