Windows and apps
Switch and close apps, windows, tabs and Spaces with the left hand, and open your most-used apps with one chord.
Window control
Tab, Q, W, A and S sit under the left hand, so you can switch and close while the right hand stays on the mouse or the navigation keys.
| Key | ⇪ | ⇪ ⌘ | ⇪ ⌥ | ⇪ ⌃ | ⇪ ⇧ |
|---|---|---|---|---|---|
| Tab | Next app (⌘Tab) | Previous app (⇧⌘Tab) | Space to the right (⌃→) | Next tab (⌃Tab) | |
| Q | Quit the app (⌘Q) | Quit the app (⌘Q) | Lock the screen (⌃⌘Q) | Log out (⇧⌘Q) | |
| W | Close the window or tab (⌘W) | Close (⌘W) | Sleep the display | Sleep the Mac | |
| A | Mission Control (⌃↑) | Show the desktop (F11) | Open Apps (Launchpad) | ||
| S | Next tab (⌃Tab) | Previous tab (⌃⇧Tab) | Next window of the app (⌘`) | Previous window of the app (⇧⌘`) |
⇪ A on its own has no binding. Sleep the display and Sleep the Mac are
built-in actions that run immediately; in the Playground's Safe Practice mode
they are only previewed.
Open apps
E, R, T, Y, F and G open apps, three per key. An app that is not installed is skipped: the key does nothing until you install it.
| Key | ⇪ | ⇪ ⌘ | ⇪ ⌥ |
|---|---|---|---|
| E | Safari | Finder | |
| R | iTerm | Preview | Terminal |
| T | Visual Studio Code | Typora | Notes |
| Y | Siri | Karabiner-Elements | Amphetamine |
| F | Alfred | Dash | Dictionary |
| G | IntelliJ IDEA | Google Chrome | Calendar |
| C | Codex | Claude |
⇪ ⌃ P, ⇪ ⌃ A and ⇪ F4 open Apps (Launchpad on older macOS).
Apps are matched by bundle ID, not by name or path, so they open wherever they are installed. To open a different app, pick the key in the keyboard editor and choose Open app.
