As a Chromebook user who's made Chrome OS my primary system for over six months—transitioning seamlessly from Windows—I've discovered powerful keyboard shortcuts that transform these lightweight laptops into productivity powerhouses. Despite common misconceptions about limited features, Chromebooks pack hidden gems. Here are 10 of the most useful ones I've relied on daily.
Skip third-party apps; Chrome OS's native screenshot tool captures any screen effortlessly. Just press Ctrl + the screenshot key (as shown below).

The shelf—your bottom taskbar—holds pinned favorites alongside the launcher and notifications. Open them mouse-free: Press Alt + (1-8), numbering from left to right.
Secure your device instantly, even for a quick break. Press Ctrl + Shift + L to lock the screen, just like on Windows or other OSes.
No dedicated Caps Lock key? No problem. Press Alt + Search key to toggle it on or off—a quirk I mastered early on.
Sign out in seconds: Press Ctrl + Shift + Q (twice quickly).
Bypass the trackpad: Press Alt + Shift + M to launch Files instantly.

Chrome OS hides a robust Task Manager. Open it with Shift + Esc, and click "Stats for nerds" for deeper insights.

View all shortcuts at once: Press Ctrl + Alt + ? for an interactive overlay.

Adjust display scaling without settings: Ctrl + Shift + + zooms in; Ctrl + Shift + - zooms out.
Extend or mirror to an external screen seamlessly. Use Ctrl + Alt + F2 (check your model; image shows key combo).
