== 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。 | |
