Abstract: Described are methods for entering and editing data strings that are inputted into cellular telephones having a screen. In one method, all basic Hangul consonants and some of the compound Hangul consonants are included in a candidate consonant list and all basic Hangul vowels and some of the compound vowels are included in a candidate vowel list. The candidate consonant and vowel lists are alternatively displayed on a component display region (906) located on the screen. For form a Korean character, a user can select consonant(s) and vowel from the candidate consonant and vowel lists. To form a compound Hangul component that is not included in either the candidate consonant list or the candidate vowel list, the user selects a basic Hangul component as a first part of the compound Hangul component from either the candidate consonant list or the candidate vowel list.

Abstract: Described are methods and apparatuses for selecting Hangul components to form Korean characters on a screen located on electronic devices. All Hangul components are divided into three groups; namely, an initial consonant group, a medial vowel group, and a final consonant group. Any Hangul components can be found in these three groups. These three group Hangul components are alternatively displayed on a component display region (1006) located on the screen. At the beginning of inputting a Korean character, the first display region displays the initial consonant group in the component display region (1006). To form a Korean character, a user selects an initial consonant from the initial consonant group. Upon the selection of the initial consonant, the component display region (1006) displays the medial vowel group. The user then selects a medial vowel from the medial vowel group. Upon the selection of the medial vowel, the component display region (1006) displays the final consonant group.
