Stacking Tones: ่ ้ ๊ ๋
See these keys on the full keyboard layout
Thai has four orthographic tone marks even though the language has five tones (the mid tone is the default and is written without a mark). You have already met mai ek ่ and mai tho ้. This skill adds mai tri ๊ and mai chattawa ๋ — two marks that appear mainly in royal vocabulary, proper nouns, transliterations, onomatopoeia, and Thai renderings of foreign words. They are genuinely less common than ่ and ้, but knowing where they live and how they fit into the keystroke sequence is essential for accurate typing whenever they appear.
Why it matters
Mai tri ๊ marks the high tone and appears in words like ก๊าซ (gas), เป๊ะ (exactly), แป๊ะ (a loose term for a Chinese-Thai elder), เก๊ก (showy), and many sound-symbolic forms such as ก๊อก (the sound of a knock). Mai chattawa ๋ marks the rising tone in a smaller set: ป๋า (dad, affectionate), ตั๋ว (ticket), จ๋า (a term of endearment), and reduplicated forms like ป๋องแป๋ง (spotless). You will not type these marks daily, but encountering one without a practised response creates a jarring mid-word hesitation.
The deeper reason for this lesson is structural: the four marks complete the keystroke grammar of Thai tone. Together they occupy three keys on the right side of the keyboard — ่ and ๋ share J, ้ and ็ share H, and ๊ shares U with ี — and every one of them lands at the same position in the syllable sequence: after the consonant (and any stacked vowel), before the trailing vowel. Master the position once with two marks, and the rarer two are just a Shift chord on a key your index finger already owns.
There is also a reason the rare marks cluster where they do: they are the marks of expressive language. ๊ and ๋ carry the high and rising tones, which Thai uses for emphasis, exclamation, and sound painting — ก๊อก for a knock, ป๋องแป๋ง for cleanliness shining, เป๊ะ for something exactly right. Writers reach for these marks in dialogue and slang far more than in formal prose, which is why you meet them in messages and stories rather than in textbooks. For the typist this is a mercy: the words are memorable because they are vivid, and the marks live on two keys that are easy to feel.
The characters
On Kedmanee the four tone marks cluster on three keys. ่ (mai ek) is on J, its base layer; ๋ (mai chattawa) is on Shift+J. ้ (mai tho) is on H, its base layer; the Shift layer of H holds ็ (mai tai khu), the short-vowel shortener of เด็ก and เล็ก — not a tone mark, but a frequent visitor on the same key. ๊ (mai tri) is on Shift+U, which on its base layer carries ี (sara ii) — the only tone mark that does not share a key with another tone mark. U answers to the right index, the same finger that owns J and H, so the whole four-mark system lives within one finger's reach.
The three keys tell a frequency story. J and H are home-row keys because ่ and ้ are the two most common marks in the language. U is one row up because ๊ is rare — but it still sits squarely in the right index's column, next to Y and above N. H's Shift layer carries ็, the hard-working shortener of everyday words like เด็ก, เล็ก, และ — และ has no ็ — แต่ and เป็ด and เล็ก. The layout's message: common marks on the resting row, rarer marks one row up, and nothing outside the index column.
The U key deserves one more look because its base layer is ี — one of the most common vowels in the language — while its Shift layer is one of the rarest tone marks. Typing ๊ therefore means pressing Shift+U where muscle memory already knows U as the ี key. That dual identity is the lesson's hidden challenge: the finger knows U at a fast, automatic level, and the Shift chord must override that speed on purpose. The drills handle it by alternating ี words and ๊ words in the same session, so the same key is felt at both layers within seconds of each other.
- ่ (mai ek) on J — right index, home row
- ้ (mai tho) on H — right index, home row
- ๊ (mai tri) on Shift+U — right index, top row; U's base layer is ี
- ๋ (mai chattawa) on Shift+J — right index, home row, the Shift of ่
- ็ (mai tai khu) on Shift+H — the short-vowel shortener, not a tone mark
The four-mark system
Each of the four marks writes a specific tone on a live syllable. ่ writes the low tone or the falling tone depending on the consonant class, as the tone-marks lesson explained; ้ writes the high tone or the falling tone. The two new marks are simpler: ๊ writes the high tone and ๋ writes the rising tone, with no class condition to consider in ordinary words. ก๊าซ is high tone on the first syllable, จ๋า is rising, แป๊ะ is high — the mark alone tells the reader, whatever consonant carries it.
The system is also a closed shape worth memorising as a whole: no mark = mid tone; ่ = low or falling; ้ = falling or high; ๊ = high; ๋ = rising. Five tones, four marks, and every mark except the bare syllable sits on the right side of the keyboard under the right index. When you meet an unfamiliar word in text, the mark tells you the tone before the dictionary does; when you type it, the mark's key is one of two home-row keys or one top-row key, always the same finger.
Mai tai khu (็) is the system's quiet fifth member. It is not a tone mark — it shortens the vowel of the syllable it sits on, turning แ- into แ็- in words like เด็ก, เล็ก, and เป็ด — but it borrows the exact same keystroke slot: after the consonant, before the trailing vowel. Its key, Shift+H, is the Shift of ้, so the chord shape is identical to ๋'s. Learning ็ here means one more Shift chord that later lessons never have to re-teach; it appears in some of the most common words in the language, so the chord more than pays for itself.
Where ๊ and ๋ actually appear
The ๊ words you will type most are short and punchy, many of them sound-symbolic: เป๊ะ (X, Shift+U, T), แป๊ะ (C, X, Shift+U, T), เก๊ก (G, D, Shift+U, D), ก๊อก (D, Shift+U, V), ก๊อกก๊อก (the knock-knock word, twice through), ก๊าซ (D, Shift+U, K — its ซ needs the Shift layer, a later lesson). Notice the Shift chord appears after the consonant in every case: ก, ๊, ... — the mark lands exactly where ่ and ้ landed in the previous lesson.
The ๋ words are fewer but beloved: ป๋า (X, Shift+J, K), ตั๋ว (ticket — ต arrives later), จ๋า (sweetheart — จ arrives later), ป๋องแป๋ง (X, Shift+J, V, quote, C, X, quote — the reduplicated 'spotless'), โป๋? — skip doubtful ones; the typeable set today is ป๋า and ป๋องแป๋ง and words built on them. Because the ๋ words are mostly nicknames, endearments, and reduplications, they cluster in informal writing — messages between friends, social media, and dialogue in stories. That is where you will meet them, and they deserve a practised key because they are exactly the words that make informal Thai feel like Thai.
Nicknames are the other home of these marks. Thai nicknames and terms of endearment freely use ๊ and ๋ — แป๊ะ for an elder, ป๋า for dad, and the pattern spreads through family chat and social media. A typist who reads Thai messages daily will meet ๊ and ๋ far more often than formal text suggests, and the pause caused by an unpractised mark is worse in fast conversation than in careful prose. Practising the two chords is therefore not an exercise in obscure orthography; it is preparation for the most casual, most frequent kind of Thai writing there is.
- ๊ words: เป๊ะ แป๊ะ เก๊ก ก๊อก ก๊อกก๊อก ก๊าซ — high tone, Shift+U.
- ๋ words: ป๋า ตั๋ว จ๋า ป๋องแป๋ง — rising tone, Shift+J.
- ็ words (Shift+H): เด็ก เล็ก เจ็บ เป็ด ช็อป — the short-vowel shortener in everyday words; not a tone mark, but the same key as ้.
The keystroke order
The two new marks take the same position as the old ones: after the consonant, after any stacked vowel, before the trailing vowel. เป๊ะ is ป (X), ๊ (Shift+U), ะ (T) — consonant, mark, vowel, three keystrokes. ก๊าซ is ก (D), ๊ (Shift+U), า (K), ซ — the mark before the า exactly as ข้าว put ้ before า. แป๊ะ is แ (C), ป (X), ๊ (Shift+U), ะ (T) — pre-posed vowel first, then the consonant, then the mark, then the vowel: the full canonical sequence with a rare mark standing in for a common one.
The complete order, once and for all: pre-posed vowel, consonant, stacked vowel, tone mark (any of the four), trailing vowel, final consonant. Every syllable you have typed since the tone-marks lesson has followed it; the rare marks change nothing except the Shift chord. Memorise the order as a ladder and the rare marks stop being special — they are ่ or ้ with a modifier key, at the same rung of the ladder.
Technique
For ๊ (Shift+U), the left hand provides Shift while the right index reaches for U — opposite-hand Shift. Do not hold right Shift for a right-hand key; crossing hands here is correct and keeps the movement smooth. The same rule applies to ๋ (Shift+J): J is a right-hand key, so the left pinky holds Shift while the right index taps J. Because J is the physical bump key and the index's natural rest position, the ๋ chord is one of the fastest Shift chords on the keyboard once the left pinky learns its job.
The ็ on Shift+H uses the same chord shape as ๋ but one key left. Practise the three chords in a row — ๋ (Shift+J), ็ (Shift+H), ๊ (Shift+U) — and notice they are the same movement at three positions on one finger's strip. The left pinky stays anchored on Shift the whole time; only the right index moves. When the shift-layer lesson arrives, this anchored-pinky habit will be the foundation of every rare consonant it teaches.
Notice the asymmetry in this lesson's technique: ่ and ้ need no Shift and are pure right-index presses, while ๊, ๋, and ็ need the left pinky to join in. That asymmetry is the bridge to the shift layer. Every rehearsal of Shift+J, Shift+H, or Shift+U is simultaneously a rehearsal of the opposite-hand rule that the next lesson will apply to dozens of characters. If you have never consciously used the left pinky before, this lesson is where it wakes up — and it will thank you in every shift-layer word to come.
- Remember the keystroke order as a stack: consonant at the base, vowel in the middle, tone mark on top — and type them bottom to top, in that logical order regardless of their visual position.
- For ๊ (Shift+U), hold left Shift with the left pinky while the right index reaches U — opposite-hand Shift; crossing hands is correct here.
- For ๋ (Shift+J), J is a right-hand home key, so again use left Shift. Since J also carries the physical bump, the Shift+J chord is very fast once the left-pinky Shift becomes automatic.
- Press Shift with the left pinky and keep it down.
- Tap the mark's key with the right index — J for ๋, H for ็, U for ๊.
- Release Shift after the tap registers.
- Type เป๊ะ and ป๋า and ก๊อก alternately, feeling the chord enter and leave on every word.
Common mistakes
The most predictable error with ๊ and ๋ is pressing the wrong Shift hand. Because right-index keys feel natural with a right-Shift hold, some typists reach for right Shift when pressing J or U — but that requires the same hand to both hold Shift and tap the key, which is biomechanically awkward and error-prone. Always use the opposite hand's Shift: left Shift for right-hand characters, right Shift for left-hand characters. If a word comes out with ี instead of ๊, the left pinky was not holding; if it comes out with ่ instead of ๋, the left pinky let go early.
A second mistake is aiming at the wrong layer of the wrong key: reaching for U and hitting Y (whose Shift is ํ, a special mark from a later lesson), or reaching for J and catching H. The three mark keys sit side by side in the index's strip, and at speed the differences are millimetres. The remedy is the same chord drills as always: slow, eyes-closed alternation of J, H, U until each key's height and position are felt, not guessed.
A third mistake is omitting the rare mark entirely when the word is unfamiliar, or guessing ๊ versus ๋ from the sound. ๊ and ๋ are not interchangeable — เป๊ะ and เป๋ะ — ก๊อก and ก๋อก — the two marks write different tones and different words, and the spelling, as always, is the only authority. When a word looks foreign, look at its mark before typing it: the mark is part of the word's identity, and the drill words in this lesson exist to make that identity stick.
- Do not hold right Shift for right-hand keys — J, H, U all take left Shift.
- Do not confuse the three mark keys' positions — J, H, U are one finger's strip.
- Do not guess ๊ versus ๋ from sound — check the word's mark before typing.
A practice plan
The drill for this lesson draws from all four tone marks plus the consonant and vowel pools you know. Because ๊ and ๋ are rare in absolute terms, the drill leans on the words where they actually live — เป๊ะ, แป๊ะ, เก๊ก, ก๊อก, ป๋า, ป๋องแป๋ง — and mixes in ่ and ้ words so the four marks stay distinct in the fingers. Begin with the chord shape: Shift+J, Shift+H, Shift+U slowly, with the left pinky anchored, before any words.
Watch for the two failure modes in your session: chords that drop the Shift (ี or ่ appears instead of ๊ or ๋) and chords that land on the wrong key (Y, H, or K appears instead of U). The first is a left-hand problem — the pinky needs its own warm-up. The second is a right-hand problem — the index needs the eyes-closed alternation. If both appear, slow everything down; the two hands are racing each other, and the chord only works when the left hand leads.
Measure the chords separately from the marks. A session that types ๊, ๋, and ็ correctly but slowly has a chord-timing problem — the left pinky leads, the right index follows, and the gap between them needs to shrink. A session that types them fast but wrong has a position problem — the index is guessing J, H, U instead of feeling them. The heatmap distinguishes the two: wrong-key misses appear as hot keys (Y, H, K), while Shift-drop misses appear as the base character's key lighting up instead. Read the pattern before choosing the next drill.
- Warm up: left pinky on Shift, right index taps J, H, U in a loop — one minute, eyes closed.
- Chord words: เป๊ะ แป๊ะ เก๊ก ก๊อก ป๋า ป๋องแป๋ง, two passes each — three minutes.
- Mixed set: the skill drill's pool with all four marks, then the heatmap's J/H/U read.
What comes next
The shift-layer lesson generalises everything you just practised: the opposite-hand Shift rule, the anchored pinky, the chord timing — all of it applies to every Shift character in the layout. The shift layer adds the rare consonants ฆ, ฌ, ณ, ญ, ฎ, ฑ, ธ, ษ, ศ, ฮ and the Thai numerals ๑–๙, plus ฤ, ฯ, ฿, and punctuation. If the chords of this lesson felt smooth, the shift layer will feel like applying one rule many times; if they felt shaky, the shift layer will expose exactly which part of the chord is weak.
After the shift layer come the special marks — ำ ั ์ ํ — and then syllable clusters, words, and rare letters. This lesson and the previous one have now covered every tone mark in the language: ่, ้, ๊, ๋, and their silent cousin ็. Whatever the next word throws at you — ข้าว, เป๊ะ, ป๋า, เด็ก — the mark's key is already in the right index, and the ladder rung is already known.

Low-frequency consonants mostly borrowed from Pali and Sanskrit sit on the Shift layer or in unexpected positions. You will not type them daily, but when they appear in a word you need to find them without breaking your rhythm.
Holding Shift unlocks a second set of Thai characters on almost every key. The governing rule — always Shift with the hand opposite the key — keeps the motion ergonomic and consistent across the entire layout.
Four marks that each do something structurally distinct — a compound vowel, a short-vowel marker, a silencer, and a nasaliser. Understanding what each mark does in the Thai writing system makes their positions far easier to remember.
