Opening Crosh with a keyboard shortcut

On a Chromebook, Crosh (the Chrome OS shell) opens with a single keyboard combination: press Ctrl + Alt + T. A terminal window will appear when ready, ready for commands. This works on any Chromebook, regardless of model or Chrome OS version. The window that opens is a black or dark-colored box with a command prompt at the bottom, waiting for you to type.

You can resize the Crosh window like any other window on your Chromebook — drag the edges or corners to make it larger or smaller, or drag the title bar to move it around your screen. If you close it and need to open it again, the same keyboard shortcut works every time. There is no setup required, no settings to change, and no special permissions needed.

Key Takeaways

  • Press Ctrl + Alt + T to open Crosh on any Chromebook, and a terminal window appears when ready without any setup.
  • Crosh only works on Chromebooks running Chrome OS, not on Windows, Mac, or Linux computers.
  • You do not need to enable developer mode or change any settings to use Crosh for basic network and system commands.
  • The terminal window can be resized, moved, and closed like any other process window on your Chromebook.
  • If the keyboard shortcut does not work, make sure you are on the Chrome OS desktop and not inside another process.

What you can do once Crosh is open

Once the Crosh window is open, you can type commands to check your network connection, run diagnostics, or access system information. Common commands include ping (to test if you can reach a website or server), ifconfig (to see your network settings and IP address), help (to list available commands), and battery_test (to check your battery health). Type a command and press Enter to run it. The results appear in the same window below your command.

If a command does not work or you see an error message, you may be trying to use a command that requires developer mode, which is a separate process not needed for basic Crosh use. Most diagnostic and network commands work in standard Crosh without any additional configuration. You can type multiple commands one after another in the same session.

Crosh versus developer mode shell

Crosh is the standard terminal available to all Chromebook users without any special setup or changes to your system. It has limits — some advanced commands and direct file system access are not available in standard Crosh. If you need deeper access to your Chromebook's system files or want to run commands that modify the operating system itself, you can enable developer mode, which opens a different shell with more capabilities.

Developer mode is not the same as Crosh. Enabling it requires a factory reset of your Chromebook and changes how your device boots up. It also removes some security protections, which is why it is not recommended for everyday use. For most users who want to run basic network tests, check system information, or diagnose connection problems, Crosh is sufficient and requires no setup at all.

Troubleshooting if Crosh does not open

If pressing Ctrl + Alt + T does nothing, check that you are on the Chrome OS desktop, not inside another process. Close any open windows or browser tabs and try the shortcut again. If you are inside a web browser, a document, or another process, that program may be capturing the keyboard shortcut instead of sending it to Chrome OS.

On rare occasions, a Chromebook update or a custom configuration can affect keyboard shortcuts. If the shortcut still does not work, restart your Chromebook and try again. After restart, press Ctrl + Alt + T on a blank desktop. If Crosh still does not respond after a restart, contact your Chromebook manufacturer or your organization's IT support, as this is unusual and may indicate a system issue that needs professional attention.

Alternative ways to open Crosh

If the keyboard shortcut does not work for some reason, you can open Crosh through the Chrome OS launcher. Press the Search key (also called the Launcher key) on your Chromebook keyboard — it is usually in the top-left area where Caps Lock would be on a standard keyboard. Type "crosh" or "terminal" and press Enter. The Crosh window will open the same way as using the keyboard shortcut.

This method is also useful if you want to remember the name of the process or if you are troubleshooting keyboard shortcut problems. The launcher search is always available on your Chromebook desktop.

Closing Crosh and returning to your desktop

Close the Crosh window the same way you close any other window on your Chromebook: click the X button in the top-right corner of the terminal window, or press Alt + F4 while the window is active. Any commands you were running will stop, and you will return to your desktop. Closing Crosh does not affect your Chromebook's operation or any files you have open elsewhere.

You can open Crosh again at any time with Ctrl + Alt + T. There is no limit to how many times you can open and close it, and each time you open it, you start with a fresh terminal window.

Frequently Asked Questions

Can I use Crosh on a Windows or Mac computer?

No. Crosh is specific to Chrome OS and only works on Chromebooks. Windows computers have Command Prompt or PowerShell as their terminal applications, and Mac computers have Terminal. Each operating system has its own command-line interface.

Do I need to be in developer mode to use Crosh?

No. Crosh is available on all Chromebooks without enabling developer mode. Developer mode is a separate process that gives you access to additional commands and system files, but it requires a factory reset and is not necessary for basic Crosh use like network testing or system diagnostics.

What if I forget the keyboard shortcut?

You can open Crosh by pressing the Search key (Launcher key) on your Chromebook keyboard, typing "crosh" or "terminal", and pressing Enter. The Search key is usually in the top-left area of the keyboard where Caps Lock would be on a standard keyboard.

Can I save the output from Crosh commands?

Crosh does not have a built-in save or export feature. You can copy text from the terminal window and paste it into a document, or take a screenshot of the window. Some advanced users in developer mode can redirect output to files, but this is not available in standard Crosh.

Will closing Crosh affect my files or settings?

No. Closing the Crosh window does not affect your Chromebook's operation, your files, or any settings. It straightforward closes the terminal process. Any other windows or applications you have open will continue to work normally.
