I suspect something like this, too, but now I checked. Indeed "showkey -s" 
does not display a scancode for Fn, so I guess we cannot do anything
about it.

Since this does not let me sleep properly :-), I installed MacOS X and
looked how it is solved there: you use the "Alt" key to enter
characters like [] {} \ etc. Obviously this is not an option for us
since Alt is needed for too many other things.

Right now I think that Colin's approach

is the sanest one.

What do you think?
