== Usage ==
In default setting,
input quickhint in lowercase
and
select charhint label in uppercase.

== SETTING ==
let g:hintchars:
    set character used by char-hint.
    e.g.)
      let g:hintchars="hjkl"
let g:hintsio:
    - "i" setting char-hint input lowercase.
    - "I" setting char-hint input uppercase.
    - "o" setting char-hint show lowercase.
    - "O" setting char-hint show uppercase.
    Default setting is "IO".
    e.g.)
      let g:hintsio="i"
let g:hintlabeling:
    - "s" setting simple n-base decimal hint labeling (n = hintchars.length)
    - "a" setting adjust no overlap labeling
    Default setting is "s".
    e.g.)
      let g:hintlabeling="a"

== TODO ==

== 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。
