Mechanics module WCAG 2.1.1 Level A

Keyboard navigation

Stelle sicher, dass du alles ohne Maus erreichen kannst. Nutze Tab, Enter, Pfeiltasten und Esc.

What it does

Function in one sentence — and in three sentences

Eine wichtige Regel heißt: Alles muss mit der Tastatur funktionieren. Das steht in den Regeln für Barrierefreiheit auf Stufe A. Das klingt einfach. Oft ist es aber schwer. Schieberegler, aufklappbare Menüs und Bildergalerien sind oft ein Problem. Das Modul prüft, ob du alles mit Tab erreichst. Es fügt auch fehlende Tastenfunktionen hinzu. Solche Probleme heißen Tastatur-Fallen. Das Modul findet und löst diese Probleme.

This is how the plugin implements it.

Technical measures

Tab-trap detection: detects when an element breaks the tab order (e.g., a modal without Esc closing).
Retrofit Enter/Space handler for `
`-Buttons with `role="button"`.
Arrow navigation in tab lists, radio groups, menus.
Esc handler for modals, tooltips, and off-canvas menus.
Focus trap in the modalTab remains in the open dialog, it does not jump to the background.

In the plugin backend

You can find these settings in the module tab.

Global Toggle
Auto-handler for `role="button"` (Enter + Space)
Focus trap in modals: off / only explicitly marked modals / all modals
Esc listener depth: top modal only / all open modals
Custom keyboard shortcuts per element (via `data-sp-key`)

Use case

Mandatory module. Keyboard accessibility is a WCAG requirement at the lowest conformance level (A) — without this criterion no WCAG compliance, no matter how beautiful the rest of the page is.
