custom binding

I have bound keycode 131 to ( and keycode 129 to ) on my jp106 keyboard. 131 is the muhenkan key to the left of my spacebar; 129 is the henkan key to the right. I’ve also bound keycode 120, which is normally supposed to toggle between katakana and hiragana, to F30. I might use this to toggle between dvorak and qwerty in the future. Stock dvorak or qwerty misplaces some useful punctuation…
