A Hangul keyboard for developers and power users — for anyone who needs Esc, Tab, Ctrl chords, function and arrow keys on a phone, and a keyboard that behaves itself in a terminal. It is small and asks for almost nothing. The APK is about 470 KB, most of that the Hanja tables, written in plain Java with no third-party runtime dependencies; the Hanja tables are memory-mapped straight out of the APK, so they cost storage rather than memory. It declares a single permission, VIBRATE — an ordinary permission, never requested at runtime, driving nothing but the buzz under your finger, which you can turn down to zero. No network, no account, no analytics. And nothing is missing for it. The keys other keyboards leave out Esc, Tab, Ctrl, Alt, Meta, F1-F12, the arrows, Home and End, PgUp and PgDn, Ins, forward-delete and PrtSc, sent as real key events rather than as characters that look like them. Modifier chords the keyboard has no use for are handed to the app, so an editor's own shortcuts keep working, and a soft Ctrl plus a letter sends a genuine control code to a terminal. Layouts * 2-beolsik, the standard full Korean keyboard. * 천지인 and 나랏글, the two 12-key phone layouts. Both compose the whole of Hangul, including every compound final — 많, 삶, 앉 and the rest. Two keys in the spare column turn the twelve keys into the phone keypad's digits or into the cursor cluster. * QWERTY, Dvorak and Colemak for English; Spanish, Portuguese, Italian, Polish, German, Turkish, French AZERTY, Greek, Hebrew, Persian, Arabic, Urdu, Thai, Hindi, Russian, Ukrainian, Bulgarian, Macedonian, Serbian, Georgian and Armenian with their own letters on their own positions; Vietnamese with Telex; Japanese by romaji or on the 12-key flick pad, typed straight into hiragana. * A symbols page, a keypad with arrows and function keys, and a menu page for edit commands. * The globe key walks the layouts you enabled, in the order you set. Typing on twelve keys 천지인 keys can be dragged instead of tappe
