Tamil99 keyboard layout is based on consonant-vowel combination. This keyboard has been announced as a standard by the Tamil Nadu state government in India. The keyboard has been optimised for fast Tamil text typing. Users who type mostly Tamil text prefer this keyboard layout.
The vowels are placed over the lower case keys on the left side of the keyboard. The akaram-consonants (ÌÅ ˆé’Æ …Æ’Ñ—ÀË) are placed over the lower case
keys on the left. The ‘pulli’ is over lower case ‘f’ and ayutham is on the upper case ‘F’. The grantha characters and other symbols are over the upper case keys on the left.
Also note that there are some shuffling of punctuation marks.
When the keyboard is in English mode (or the default system mode), you will not be seeing Tamil characters when you depress the keys. What you will see are the bold characters on the left of each keycap in figure TK1.
When you switch keyboard mode to Tamil with the F12 key, you will get the characters on the right of the keycaps when you press these keys.
To get the other Tamil letters that are not on the keyboard, you use the conso- vowel combination. Some examples are given below:
