== Usage ==
In default setting,
input quickhint in lowercase

select charhint label in uppercase.
== OPTIONS ==
set histchars="hjkl":
show char-hint use h, j, k, l.
set charhintinput=uppercase|lowercase:
charhint input in uppercase|lowercase
set charhintshow=uppercase|lowercase:

<detail lang="ja"><![CDATA[
== Usage ==
デフォルトの設定では
小文字は候補を絞るためのテキスト入力に、
大文字は文字ラベルの選択に使います。
