impossible to remap keys on japanese keyboard

[Troy]

Hi, 

When mapping keys to modifiers, you should alter the
modifier map instead.

To get the modifier map, use:
xmodmap -pm

To add the Hiragana_Katakana key, use:
xmodmap -e 'add Shift = Hiragana_Katakana' 

Will should add Hiragana_Katakana to the shift modifiers.
I did notice that this doesn't work, although it seems
that it should.... 

I then tested with another key, Henkan.

xmodmap -e 'add Shift = Henkan' 

This works.

If you look at the xev output, you will see that the 
state is changed after pressing and releasing the
newly mapped "keycode 208 Hiragana_katakana/Romaji" key,
as it is for Henkan as well. I.e. the state is 0x1 in
the key released output (indicating state when the key was 
still down).

I unfortunately just upgraded by only Ubuntu 5.10 to Ubuntu 6.06,
so I couldn't test with 5.10. 

In conclusion, I thought I knew how this works, but I am now
baffled as well. Sorry. I will foreward this question to the
xkb list, which is a better forum.
