| 969 ;; defining button2 in the minibuffer keymap to | |
| 970 ;; `minibuffer-smart-select-highlighted-completion', and setting the | |
| 971 ;; mode-motion-hook of the minibuffer to `minibuffer-mouse-tracker'. | |

| 973 ;; mode-motion-hook apply (for mouse motion and presses) no matter | |
| 974 ;; what buffer the mouse is over. Then, `minibuffer-mouse-tracker' | |

| 986 ;; -- unless you're aware of the "filename in any buffer" feature, | |

| 988 ;; as a bug | |

| 990 ;; | |
| 991 ;; There's some hackery in minibuffer-mouse-tracker to try to avoid the | |
