Erik Andersen | 13456d1 | 2000-03-16 08:09:57 +0000 | [diff] [blame] | 19 | Terminal key codes are not extensive, and more will probably |
| 20 | need to be added. This version was created on Debian GNU/Linux 2.x. |
| 21 | Delete, Backspace, Home, End, and the arrow keys were tested |
| 22 | to work in an Xterm and console. Ctrl-A also works as Home. |
Mark Whitley | 4e33875 | 2001-01-26 20:42:23 +0000 | [diff] [blame] | 23 | Ctrl-E also works as End. |

Eric Andersen | 5f2c79d | 2001-02-16 18:36:04 +0000 | [diff] [blame] | 25 | Small bugs (simple effect): |
| 26 | - not true viewing if terminal size (x*y symbols) less |
