Write in Khmer
Write in Khmer using the keypad.
To type in the normal consonant or independent vowel and its subscript format, press the same key.
Type in a subscript consonant
To signal that the next consonant is a subscript consonant, insert the artificial character, coeng. This
forces the following consonant or independent vowel to become a subscript character. To insert the
coeng, press 1.
A consonant shifter is used to change the sound of a vowel that accompanies a consonant. When it is
followed by a vowel that needs to be placed above the consonant, the consonant shifter changes its
position automatically, so it is placed under the main consonant.
