TIER 1 --- Large screen differentiated
| **Objective:** Make your app[large screen differentiated](https://developer.android.com/docs/quality-guidelines/large-screen-app-quality#large_screen_differentiated)by meeting the[LS-I10](https://developer.android.com/docs/quality-guidelines/large-screen-app-quality#LS-I10)through[LS-I16](https://developer.android.com/docs/quality-guidelines/large-screen-app-quality#LS-I16)keyboard, mouse, and trackpad requirements of the[Large screen app quality](https://developer.android.com/docs/quality-guidelines/large-screen-app-quality)guidelines.

Large screen differentiated apps support keyboard, mouse, and trackpad features equivalent to those of web or desktop apps, including:

- A comprehensive set of keyboard shortcuts in addition to conventional shortcuts such as<kbd>Ctrl-C</kbd>for copy and<kbd>Ctrl-Z</kbd>for undo
- Keyboard and mouse or trackpad combinations, such as<kbd>Ctrl+click</kbd>or<kbd>Ctrl+tap</kbd>and<kbd>Shift+click</kbd>or<kbd>Shift+tap</kbd>, for enhanced capabilities such as the selection of ranges of adjacent items or multiple separated items
- Scrollbars while content is being scrolled using a mouse or trackpad
- Additional content such as fly-out menus or tooltips on mouse or trackpad hover over UI elements
- Desktop-style menus and context menus
- UI panels in multipanel layouts that are movable and resizable using a mouse or trackpad
- Triple clicking or tapping using a mouse or trackpad to select entire lines or paragraphs of text
