How to Turn Off the Touchscreen on a Chromebook?

Step-by-step

1. Open Chrome and type chrome://flags into the address bar, then press Enter.
2. In the search box at the top, search for "debugging keyboard shortcuts".
3. Find the flag named "Debugging keyboard shortcuts" (#ash-debug-shortcuts) and change it from Default to Enabled.
4. Click Restart to reboot your Chromebook and apply the change.
5. After it restarts, press Search + Shift + T to toggle the touchscreen off.
6. Press the same shortcut again to turn the touchscreen back on.

(On some Chromebooks the Search key is the Launcher/Everything button; on others you may need *Ctrl + Alt + Shift + T*.)

Why turn it off?

• To stop accidental taps while typing or cleaning the screen.
• To prevent "ghost touches" if the screen is faulty or cracked.
• To reduce distractions for kids or in a classroom setting.

Things to know

• The flag is a developer/experimental feature, so its name or behavior can change between Chrome OS versions. If the shortcut doesn't work, double-check the flag is Enabled and that you restarted.
• The setting typically persists across restarts, but a Chrome OS update can reset flags — you may need to re-enable it.
• You can disable the touchpad the same way using Search + Shift + P.
