Lesson 01 · Keyboard · Practice
Find the barriers.
The page below is for Northwind, a fictional product. It looks finished and it works with a mouse. Five keyboard barriers are hidden across it. Your job is to find them.
Your task
Put the mouse down. Using only Tab, Shift+Tab, Enter, Space, the arrow keys and Esc, try to do everything on the page: start a trial, watch the demo, switch the billing period, open the currency menu, and request an invite. The status line at the bottom reports each action that fires.
Note everything you cannot reach, cannot see, or cannot trigger. When you are ready, open the breakdown to check what you found.
