| 20 | Usage and Known bugs: |
| 21 | Terminal key codes are not extensive, and more will probably |
| 22 | need to be added. This version was created on Debian GNU/Linux 2.x. |
| 23 | Delete, Backspace, Home, End, and the arrow keys were tested |
| 24 | to work in an Xterm and console. Ctrl-A also works as Home. |
