Yep, commenting the two case lines brought my tilde key back. Any idea
what the ukbd_apple_swap() function was _supposed_ to be doing?

Also, there's only one thing left (input-wise) that I can't get to
work, and that's the 'delete' key (Fn+Backspace). I'm pretty certain
that it's not a problem with Fn+Backspace failing to map to Delete,
because my non-Mac i386 box has the same problem.

Everything I read online keeps saying to muck with an .inputrc file
(for bash, anyway), but I haven't been able to get it to work. Places
I've looked have said to add this to .inputrc:

"\e[3~": delete-char

But this seems to have no effect (and I tried bind -f .inputrc in case
my INPUTRC environment variable wasn't working). Is there something
FreeBSD-specific I'm not seeing, or what?
