+# Rectangle
+
+window management for macOS. keyboard shortcuts to snap windows to halves, thirds, quarters, etc.
+
+**installed via:** `brew install --cask rectangle`
+
+**use case:** quick window tiling without a full tiling window manager. the keyboard shortcuts (ctrl+opt+arrow keys) become muscle memory fast.
+
+**also installed:** Amethyst (`brew install --cask amethyst`) — a full automatic tiling WM. Rectangle is lighter for basic snapping when you don't want everything auto-tiled. also tried AeroSpace (`brew install --cask aerospace`).
+
+**keyboard theme:** part of the broader keyboard-driven workflow alongside [[Karabiner-Elements]], [[Homerow & Vimium|Homerow]], and [[Vimium]].
