Backspace undid a keystroke: な became ん, かんじ became かんj, きゃ
became ky. Like every Japanese IME it now deletes the last kana as
shown — な goes, かんじ becomes かん, きゃ becomes き — while a romaji
letter that never became kana still goes one at a time. Tab stepped
through candidates in a search and committed in Japanese; it steps
through them there too, with Space, and Shift+Tab steps back.
