Open Chrome and go to a new tab. Click the more options button at the top right (the one with three dots), and from the menu, select More Tools>Developer Tools. Alternatively, you can tap the F12 key or the Ctrl+Shift+I key to open Developer Tools in Chrome.
Once the Developer Tools, or the developer console is open, click the more options button (again, three dots), and select the Run Command option or, just tap the Ctrl+Shift+P keyboard shortcut. This will activate the command input field.
