TIER 2 — Large screen optimized
Apps optimized for large screen devices provide an enhanced,
accessibility‑compliant user experience by supporting advanced keyboard,
mouse, and trackpad input capabilities, including:
- Keyboard navigation using the Tab and arrow keys
- Keyboard shortcuts for actions such as select, cut, copy, paste, undo, and
redo
- Keyboard control of media playback, such as using the Spacebar to
play and pause media
- Keyboard send function in communication apps using the
Enter key
- Options menus accessible by mouse and trackpad right‑click behavior
(secondary mouse button or secondary tap)
- App content zoom (magnification) using trackpad pinch gestures and the mouse
scroll wheel with the Ctrl or Control key
- Hover states for interactive UI elements
