28 | ;; Should work well for Televideo TVI 925 although it's overkill. |
29 | ;; | |
30 | ;; The Wyse50 is ergonomically wonderful, but its escape-sequence design sucks | |
31 | ;; rocks. The left-arrow key emits a backspace (!) and the down-arrow a line | |
32 | ;; feed (!!). Thus, you have to unbind some commonly-used Emacs keys to | |
33 | ;; enable the arrows. | |

121 | ;; On killing (C-x C-c) the end inverse code (on column 1 of line 24) | |
122 | ;; of the mode line is overwritten AFTER all the y-or-n questions. | |

124 | ;; scrolled of the screen. Suspending (C-z) does not cause this problem. | |
