kaku offers the twenty-two readings of かく before 書く, because the SKK
dictionary keys a verb by its stem and gives no frequency to rank the two
lists by. SKK's own answer is the shift key: kaKu says where the
okurigana starts, and that split now comes first — the reading's own
candidates still follow it. Caps Lock sends no Shift, so it marks
nothing, and a word typed without Shift is unchanged.
