Sabdalipi uses a phonetic style keyboard in the sense that the key for a particular Assamese character is the similar sounding English character.
For example k is ক, g is গ, p is প and so on.
Similarly uppercase characters are used for the deep sounding characters.
For example K is খ, G is ঘ, P is ফ and so on.
The plus '+' sign is used to create juktyakhars
For example typing 'l+p' would result in ল্প
and typing 'j+j+b' would result in জ্জ্ব
A special key is reserved for all kaar jogs
For example a stands for Aakaar
u stands for Ukaar, i.e pu gives পু, ru gives ৰু and gu gives গু
y stands for rhokaar, i.e gy is গ্ৰ, ty is ত্ৰ and ky is ক্ৰ
The keyboard layout and kaar jogs are shown below.
