Individual skill
accessibility-operable
Use this skill when the question is whether users can *operate* a UI — keyboard, switch device, voice, screen-reader gestures — not just by mouse or touch. Trigger when designing keyboard navigation, focus management for modals/menus/popovers, drag-and-drop with alternatives, motion-heavy interactions, or any flow that asks the user to do something. Covers WCAG Principle 2 (Operable). Sub-aspect of `accessibility`; read that first if you haven't already.

# Accessibility — Operable
WCAG Principle 2: user-interface components and navigation must be operable.
The five sub-criteria, simplified:
1. **Keyboard accessible** — everything that works with mouse must work with keyboard.
2. **Enough time** — timing-out interactions are warned and extendable.
3. **Seizures and physical reactions** — no flashing content; respect motion preferences.
4. **Navigable** — users can find content and know where they are.
5. **Input modalities** — touch and other input methods supported with adequate target size.
## 1. Keyboard accessible
