The Thai Typing Trainer helps you to learn to type in Thai in a series of 52 graded lessons.
To use it, read the notes for each lesson, then type the Thai text displayed towards the bottom of the screen. As you type the current letter to be typed will be displayed in blue. If you make a mistake the letter will turn brown and you'll need to try again. As you complete a line, the next line will be displayed until the current lesson is complete. You'll then be presented with a screen which gives you the choice either to repeat the lesson, or move on to the next one. At any time you can also use the box in the bottom right of the screen to jump directly to any of the 52 levels.
For the longer notes you may need to scroll down to see all the text. A scroll bar will appear next to the notes when this is the case.
Click on the "hide" link to hide the notes.
Your keyboard must be set to Thai language before you start typing. If it's not, you'll see the "Last character typed" field shows a non-Thai character.
(The course assumes that your keyboard uses the Thai Kedmanee layout. This is overwhelmingly the most common Thai keyboard layout.)
