Best Thai Keyboard – แป้นพิมพ์ไทย
How this keyboard works
Write Thai characters by clicking on the corresponding letter on the screen (or typing with your keyboard). What you write will appear in the text area above the keyboard.
Most keys have two different Thai letters. If you click or hold the SHIFT key, you'll see the other letters.
When you're finished writing Thai script, mark the text and copy it. You may then paste it into a word document or whatever you are up to.
