Lmg Arun Keyboard Layout ((full)) (720p — 8K)
Here’s a detailed write-up on the LMG Arun Keyboard Layout:
Numbers & punctuation (Fn layer example)
Fn + top row → 1 2 3 4 5 6 7 8 9 0
Fn + home/right-side keys → common punctuation: . , ? ! - _ = + / \
Arrow/navigation layer (Fn+another modifier): Home, End, PgUp, PgDn, ← ↓ ↑ → mapped to easy-to-reach home-row keys.
Typical keymap (illustrative 3×10 layout; top row = numbers layer on Fn)
Legend: Rows shown as top→home→bottom; each row left→right.
Top row (QWERTY digits layer when Fn not held): 1 2 3 4 5 6 7 8 9 0 lmg arun keyboard layout
Alphanumeric layer (default): Q → P → Y → F → G → C → L → U → O → ; A → R → S → T → D → H → N → E → I → ' Z → B → M → V → K → W → X → J → , → .
(Interpretation: high-frequency letters like R, S, T, D, H, N, E, I are on home row; vowels distributed ergonomically.)
Layout Snapshot (Alphas only)
While full keymaps vary slightly by implementer, a typical LMG Arun layout for a 30–34-key board (e.g., without number row) looks like:
Left hand
A O E U (home)
Y I ' - (top)
W B G V (bottom) Here’s a detailed write-up on the LMG Arun
Right hand
N T R S (home)
H D L C (top)
M P K F (bottom)
(Note: exact placements may vary; some Arun variants move H or C.)
Thumbs typically handle space, backspace, enter, and layers.
2. Vowel Matras (The Killer Feature)
In Devanagari, vowels attach to consonants (e.g., का vs क). On standard layouts, typing "का" requires shifting to a number row or reaching far. In LMG Arun: Numbers & punctuation (Fn layer example) Fn +
- The ा (aa matra) is mapped to
A(easy left pinky/index). - The ि (i matra) is mapped to
I(right index). - The े (e matra) is mapped to
E.
This allows you to type "के" (ke) by pressing K (for क) + E (for े) without moving your hand off the touch-typing base.
Where to Find It
The LMG Arun is not a mass-produced product. It is typically:
- Open-source hardware: PCB designs and case files available on GitHub (search “LMG Arun”).
- Group buys: Small batch releases through Little Makers Group or r/mechmarket.
- DIY builds: Hand-wired versions using Pro Micro or RP2040 controllers.
3. Conjunct Characters (Half-forms)
Sanskrit is famous for clusters like "त्र" (t+ra), "ज्ञ" (gya), and "श्र" (shra). General phonetic layouts require you to type t + halant + r to get "त्र". LMG Arun introduces dedicated dead keys and shift-state overrides.
For example:
Z+Rusually produces a specific conjunct unique to Vedic texts.- The layout uses the
\key as a smart halant. Pressing it once applies a halant to the previous consonant; pressing it twice enters a "half-form" mode.
