+# Launcher Keyboard & Controller Navigation
+
+Issue: <https://github.com/aarmea/shepherd-launcher/issues/20>
+
+Summary:
+- Added keyboard/controller navigation for the launcher grid (arrow keys, WASD, D-pad) with focus movement between tiles.
+- Enabled focus styling on tiles and ensured the grid focuses the first tile on state updates.
+- Added keyboard shortcuts to close the launcher (Alt+F4, Ctrl+W, Home).
+
+Key files:
+- crates/shepherd-launcher-ui/src/app.rs
+- crates/shepherd-launcher-ui/src/grid.rs
+- crates/shepherd-launcher-ui/src/tile.rs
