+" Unlike Japanese or Chinese, modern Korean texts do not depends on conversion
+" to Hanja (Chinese character). Thus, general Korean text totally can be
+" covered without help of IME but this keymap. 
+" 
+" BUT, simply mapping each letter of Hangul with sequence of alphabet 1 by 1
+" can fail to combine Hangul jamo (conconants and vowels) right.
+" For example, sequentially pressing `ㅅㅓㅇㅜㄹㄷㅐㅎㅏㄱㅛ` can not only be
+" combined as `서울대학교`, but alse `성ㅜㄹ댛ㅏㄱ교`, which is totally 
+" nonsense. 
+" Though combining Hangul is deterministic with law that each letter must be 
+" one of (consonant + vowel) or (consonant + vowel + consonant), there is no
+" way to apply such law without implementing input engine.
+"
+" Thus, user of this keymap should wait until previous hangul letter is
+" completed before typing next one. To reduce such inconvenience, I suggest to
+" set `timeoutlen` as their own value. (default value is 1000ms)
