Keyboard Accessibility

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.

Critical

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.

AI

Modal Focus Management

AI-guided testing of dialog focus trapping: initial focus, tab cycling within modal, Escape to close, and focus restoration.

AI

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

TabMove forward through interactive elements
Shift + TabMove backward through interactive elements
EnterActivate links and buttons
SpaceActivate buttons, toggle checkboxes
Arrow KeysNavigate within components (menus, tabs, radios)
EscapeClose dialogs, cancel actions
