₹              AltGr + 4

Following are the conjuncts formed in our language, shown along with the keys to reproduce them:

Case 1:
CHILLU aksharam:
(i) ന്‍   =   ന + ് + zero width joiner(zwj)
ie,    key 'v' + key 'd' + key <AltGr+1>

(ii) ല്‍   =   ല + ് + zero width joiner(zwj)
ie,    key 'n' + key 'd' + key <AltGr+1>

(iii) ര്‍   =   ര + ് + zero width joiner(zwj)
ie,    key 'j' + key 'd' + key <AltGr+1>

(iv) ണ്‍   =   ണ + ് + zero width joiner(zwj)
ie,    shift key 'c' + key 'd' + key <AltGr+1>

(v) ള്‍   =   ള + ് + zero width joiner(zwj)
ie,    shift key 'n' + key 'd' + key <AltGr+1>
         
Case 2:
(i) ങ്ങ   =   ങ +  ്  +  ക
ie, shift key 'u' + key 'd' + key 'k'

ie, shift key 'u' + key 'd' + shift key 'u'

(iii) ച്ച   =   ച + ് + ച
ie, key ';' + key 'd' + key ';'

(iv) ഞ്ഞ   =   ഞ + ് + ഞ

ie, key 'c' + key 'd' + key 'c'

(x) ല്ല   =   ല + ് + ല
ie, key 'n' + key 'd' + key 'n'

(xi) വ്വ   =   വ + ് + വ
ie, key 'b' + key 'd' + key 'b'

(xii) യ്യ   =   യ + ് + യ

ie, shift key 'n' + key 'd' + shift key 'n'

(xvi) റ്റ   =   റ + ് + റ
ie, shift key 'j' + key 'd' + shift key 'j'

Case 4:
(Following conjuncts are explained with the help of consonant 'ക')

(1) Conjuncts formed with ര (ra):
 ക്ര   =   ക + ് + ര
ie, key 'k' + key 'd' + key 'j'

(2) Conjuncts formed with യ (ya):
 ക്യ   =   ക + ് + യ
ie, key 'k' + key 'd' + key '/'

(3) Conjuncts formed with വ (va):
 ക്വ   =   ക + ് + വ
ie, key 'k' + key 'd' + key 'b'

Special case:

ന്റ   =   ന + ് + റ
