| 6. | The real magic, though, is that we can create an infinite number of indices, each one representing its own key and containing a copy of the token. |

| 10. | Touch screens can display soft keyboards if they are large enough; each virtual key should be large enough to make it difficult for the user to accidentally mistype. |
