Couple of weeks ago, Kinige launched a free Telugu typing tutor. It teaches the InScript keyboard layout, which is standardized by the Indian Government. (InScript layout can reduce as much as 20% keystrokes when compared to phonetic methods.) Here is a screen shot of the Kinige Telugu Typing Tutor:
Unlike other Telugu typing tutors, the lessons in the Kinige typing tutor are cleverly designed to introduce the key positions—instead of alphabets.
The web interface shows statistics like speed, accuracy and time per session. If you want to keep track of your progress over chapters and lessons, you can create a free account in Kinige.
I hope this would help more people learn InScript and enjoy faster Telugu typing.
