This is how I do this exercise. No mouse required: 1. `cmd - shift - /` to jump to Help (works in any app) 2. type `tab` ["Hmm, I don't know exact shortcut to <undo close tab>, so let me start with something generic..."] 3. search through results with ctrl-n or ctrl-p. 4. As you search, different menu items show you the shortcut And voila, your `cmd - shift - t` is the second result under "reopen closed tab" EDIT: formatting bullets
