- Swipe left to demote an app to the bottom (swipe left again to restore)
- Long-press for Edit Tags, App Info, and more
**D-Pad** — From the search field, press down to close the keyboard and move into the list, or right to clear the search (or open the menu when it's empty). In the list, up and down move the selection, center launches, left returns to the search field, and right opens the menu. Hold left to promote an app (pin or restore it), hold right to demote it (unpin or move it to the bottom), and hold center to open or close the app menu.
**Settings** — Toggle icon visibility, color mode, theme, sort order, auto-focus, status icons, and demoted app visibility from the menu.
