Of course, I have Thai keyboard. Computers sold in Thailand have both sets of characters appear on keyboard buttons. An 'A' key, for example, have letters 'ฟ' for lower case and 'ฤ' for upper case. We have many characters so we put two for one key.
A computer can be set in its Control Panel to be able to change sets of input method. (Thai and English for most Thai computers.) Usually, we use the grave accent button as a switch button between Thai and English. Then 'ฟ' and 'ฤ' are just like 'a' and 'A', but for Thai keyboard.
I'm glad to know this. Our writing system is dubbed as the 'most complicated writing system' by YouTuber Xidnaf. You can watch his video for the explanation. There is a small error with that, but the overall video is awesome.
