As to implementing Plan 9's keyboard handling, am I right in assuming you mean for the purpose of writing programs for such a clean interface? If so, you might want to try linking with the plan9port libraries. Alternatively (and probably better) just write for Plan 9 and import your Linux file systems. Drawterm and 9vx provide very easy access to the host's files and u9fs isn't far behind. Almost all the editing and shell operations I do on my Linux box these days are done via drawterm, the only exception being root-owned files. By the way, if you run p9p acme on Linux as root, don't use win. The pty subsystem crashes or something; you have to reboot before you can open any X term. :D -- This is obviously some strange usage of the word "simple" that I was previously unaware of.
