Thai Keyboard Test
The tester drawn as a Thai Kedmanee keyboard, the layout on virtually every keyboard sold in Thailand.
ไทย (เกษมณี)·ANSI
The Kedmanee layout
Kedmanee is the Thai standard, descended from typewriters. Every key carries four legends: the Latin letter and its shift in one corner, the Thai character and its shift in the other. The home row types ฟ ห ก ด เ ้ ่ า ส ว ง, common consonants sit on the top row and the tone marks ่ ้ ๊ ๋ and vowels are reached with Shift. The number row types Thai punctuation and vowels unshifted and Thai digits ๑–๙ with Shift. Thai keyboards are ANSI-shaped, so there are no extra physical keys to worry about.
Testing a Thai keyboard
Detection is by physical key, so every key lights up whether Thai or English input is active — a big improvement for Thai users, because older testers only recognised Latin characters. Press each key and watch its counter. Combining marks such as tone marks are shown with a dotted circle on the virtual keycap so you can find them; on the record bar above the keyboard you see the exact character you typed.
Why do keys show Latin letters when I type?
The system is in English mode; press the grave key (~) or Alt+Shift to switch to Thai, depending on your settings. The keyboard is not faulty. If a specific Thai character never appears but the key lights up here, the switch works and the problem is the software layout, not the hardware.
