HOW TO USE
You must use Google Chrome.
You must be on a device that features a reload button on the keyboard. (Such as a Chromebook.)

Go to the following URL and set "Show bookmarks bar" to true.
chrome://settings/appearance

Create a new bookmark and set the URL to this code. I'd recommend leaving out the instructions.
Test it on a normal website first.

Once you've confirmed that it works, go to the test/whatever using Lockdown Browser.

Press the reload button and exit fullscreen.
You will have less than a second to click on the bookmark before Lockdown Browser fullscreens again.
If you do manage to click it in time, you will see an X button in the top right corner of your screen.
Click the button to open/close the bypass.
