1. Alt + backspace
The backspace key deletes the character to the left of your cursor. Windows PCs, however, have a separate delete key that deletes characters to the right of the cursor. To get this Windows delete-key functionality on a Chromebook, just hold down the Alt key when you backspace.2. Ctrl + 'switch window' key
The switch window key is usually found in the F5 spot on a Chromebook keyboard. Combined with the Ctrl key, it takes a screenshot of your entire desktop and saves it to your Downloads folder. To take a screenshot of only a portion of your desktop, use Ctrl + Shift + switch window key.
3. Shift + Escape
This is the Chrome OS equivalent of Windows' Ctrl-Alt-Delete. Shift-Esc calls up Chrome's Task Manager where you can see which apps are using the most system resources and force quit an unresponsive app. This keyboard shortcut only works when Chrome is your active window; it won't work if you have an app as its own window as your top-most, active window.
