>Description:
Unlike some small computers, the U.S. version of the Jornada 720 has a
software Fn key. This key, as expected, is used to get at characters
on the keyboard that are not given a discrete key as they normally
would on a full sized keyboard. This key typically isn't the Meta or
Alt keys nor the Shift or Control.
In particular, on the U.S. Jornada you need to use the Fn key to get
access to the ~, `, English sterling, International currency, {, }, [,
], and capslock keys.
>How-To-Repeat:
Try to generate a tilde character from the U.S. Jornada keyboard. Try
to figure out how to make the key maps deal with this.. fail at
both...
>Fix:
The following two patches create a software Fn key by messing with the
keycodes coming from the keyboard. This is probably done all wrong,
and I have no idea how this will interact with X or if it will cause
problems on non-US Jornada. The later probably is a problem as
keycode 102 is used for other things on those keyboards. I couldn't
tell if wscons did this sort of thing in a better way. I tried using
KC_MultiKey and others without any joy.
