Next, if you press (6) key, 'ㅏ' is inputted and (consonant) is automatically displayed to indicate that the consonant input status. If you press (9) key, 'ㄹ' is inputted and (vowel) is automatically displayed to inform you that the vowel input status. Later, in the case of 'bright' input, ㄺ is a double consonant, so it is necessary to enter 'ㄱ' after 'ㄹ', so the consonant / vowel input state is converted using the (#) key to make the consonant input state.

If you press (7), 'ㄱ' is inputted and (collection) is automatically displayed to indicate that it is in the vowel input state. In this case, in case of 'bright', the consonant / vowel input is converted back to (#) for 'c' input, thereby making the consonant input state. After that, if you press (6), 'c' is inputted and (collection) is automatically displayed to indicate that the vowel input is in progress. Finally, press (6) to enter 'ㅏ' and it's bright.

In addition, an example of the input of the "flow support" will be described.

First, when the Hangul input mode is switched, the initial state is (consonant) to indicate that the consonant input state. After pressing (9) key, 'ㄹ' is inputted and (vowel) is automatically displayed to indicate that it is in vowel input status. (7) Press the key, 'ㅠ' is input and (consonant) is displayed automatically, indicating that the consonant input status. Next, press the (4) key and 'ㅈ' will be inputted and (collection) will be automatically displayed to indicate that the vowel is in the input state.

If you press (0), 'ㅣ' is input and (consonant) is automatically displayed to indicate that the consonant input state. After pressing (8) key, 'TT' is input and (consonant) is automatically displayed to indicate that the consonant input status.

In order to input 'ㅝ', it is necessary to continuously input vowel 'ㅜ' after 'TT', so enter (#) to convert the vowel / vowel input to enter the vowel input state. Next, press the (4) key and 'ㅓ' will be displayed automatically and (consonant) will be displayed to indicate that the consonant input status. Finally, press (3) and enter 'b' to complete 'Ryu Jiwon'.

In this case, it can be implemented as a total of nine dial inputs (9) (7) (0) (0) (8) (#) (4) (3). This is the case when the computer keyboard has one more stroke than the '9' stroke.
