| 1906 | FOCUS-FRAME after reading an event typed at FRAME. |

| 1912 | a surrogate minibuffer frame when a frame doesn't have its own |
| 1913 | minibuffer window. |

| 1916 | FOO is selected, and then a different frame BAR is selected, any |

| 1918 | focus to BAR. This allows focus redirection to work properly when the |
| 1919 | user switches from one frame to another using `select-window'. |
| 1920 | |
| 1921 | This means that a frame whose focus is redirected to itself is treated |
