The seperate keymap issue is one I hadn't thought of since I'm in US-ASCII land. ;-) It could actually make a fair bit of sense to hook keyboards up that way. On the other hand, getting the single keymap case working and doing it well would be a huge step in the right direction. -- Brooks --=20 Any statement of the form "X is the one, true Y" is FALSE.
