Keyboard Navigation Testing
Automated keyboard accessibility testing with tab order simulation, focus trap detection, and AI-guided custom widget evaluation. Ensure every user can navigate your site without a mouse.
What Blyxo Tests
Comprehensive keyboard testing combining DOM inspection, browser simulation, and AI evaluation
Tab Order Simulation
Simulate keyboard navigation by pressing Tab through all interactive elements. Verify logical focus order matches visual layout.
Focus Indicator Analysis
CSS analysis of focus indicators on interactive elements. Detect outline:none without alternative focus styles via custom checks.
Keyboard Trap Detection
Simulate 20 Tab presses to catch keyboard traps where focus cannot escape. Critical for modals, iframes, and custom widgets.
Skip Link Verification
Detect and validate skip-to-main-content links. Verify they are properly positioned as the first focusable element.
Modal Focus Management
AI-guided testing of dialog focus trapping: initial focus, tab cycling within modal, Escape to close, and focus restoration.
Custom Widget Support
Claude evaluates keyboard support for tab panels, accordions, dropdown menus, carousels, and date pickers.
Character Key Shortcuts
Detect single-character keyboard shortcuts (data-shortcut, data-hotkey) that need escape mechanisms per WCAG 2.1.4.
Mouse-Only Interaction Detection
Flag elements with mousedown handlers without keyboard equivalents. Catch click handlers that bypass keyboard users.
Positive Tabindex Detection
Detect problematic positive tabindex values that disrupt natural tab order and create unpredictable navigation.
Essential Keyboard Commands
Every interactive element on your site must work with these keys
Automated Tests + Manual Procedures
Blyxo's Coverage Report provides step-by-step manual keyboard test procedures for modal dialogs, dropdown menus, carousels, accordions, and forms — with exact keyboard shortcuts and expected outcomes for every component detected on your site.
