Hi tech@

I've been frustrated with the keyboard behaviour on my MacBook Air and
started digging into wsconsctl. I could have saved myself a bit of time
if the man pages or FAQ had examples on how to create custom keyboard
mappings. Here's a diff that adds this information to the man page.

It seems that you are not stuck with the built in keyboard mappings and
are free to even create an entirely new mapping if you need it.

ok?
