第 1 层级 - 针对大屏设备提供差异化体验
与众不同的大屏设备应用支持与网络应用或桌面应用等效的键盘、鼠标和触控板功能，包括：
- 一整套键盘快捷键，以及传统快捷键，例如：使用 Ctrl-C 进行复制，使用 Ctrl-Z 进行撤消
- 键盘和鼠标或触控板组合（例如 Ctrl+点击/Ctrl+点按和 Shift+点击/Shift+点按），用于实现增强功能，例如选择一定范围内的相邻项或多个分隔开来的项
- 当用户使用鼠标或触控板滚动内容时，滚动条会显示
- 当鼠标光标或触控板悬停在界面元素上时，显示其他内容，例如飞出菜单或提示
- 桌面设备样式的菜单和上下文菜单
- 在多面板布局中，可使用鼠标或触控板移动和调整界面面板的大小
- 使用鼠标或触控板点击或点按三次即可选择整行或整段文字
