Short Answer 
You can access the Inspect Element feature on a Chromebook using three methods: right-clicking on the webpage and selecting ‘Inspect’, pressing the F12 key, or using the keyboard shortcut Ctrl+Shift+I. Each approach opens the Chrome Developer Tools for inspecting the webpage’s code, though functionality may be restricted in some environments.
Step 1: Right-Click Method
To access the Inspect Element feature on your Chromebook, start by using the right-click method. Simply navigate to the webpage you want to inspect, then perform a right-click on the page. From the context menu that appears, select the option labeled ‘Inspect’. This action will open the Chrome Developer Tools, allowing you to see the underlying code of the page.
Step 2: Using F12 Key
If you prefer using the keyboard, you can press the F12 key. This function key is specifically designed to open the developer tools directly. However, make sure that your keyboard has this key available; if not, you might need to explore other options. Once pressed, the Chrome Developer Tools will be displayed, giving you access to inspect the HTML, CSS, and JavaScript.
Step 3: Keyboard Shortcut
An alternate keyboard method to access Inspect Element is by using the shortcut Ctrl+Shift+I. Press these three keys simultaneously while on the webpage of interest. This shortcut provides a quick way to open the Chrome Developer Tools without using the mouse. Keep in mind that these functionalities may be disabled by some school systems, preventing access to the developer tools.
