Function Registry.

Search for what you want your keyboard to do, compare QMK/VIA solutions for different host systems, and copy an exact code. Built from official references and carefully labelled community observations.

Already used VIA Any keys?

You’re ready. Find a function before hunting for a code; you don't have to be a firmware developer.

Different keyboard, same workflow.

Reuse code from a working ANSI, ISO, 60% or 75% board. Studio lets you transfer individual keys without reconnecting the source board.

The host layout changes the answer.

Windows HU 0 / í, macOS HU #, and French AZERTY ß may need different solutions. Search by OS and active computer layout.

Codes are kept exactly as originally recorded. A(KC_3) and LALT(KC_3) are equivalent modifier notation; RALT/ALGR is a different modifier. Copying does not alter any board or Vault data.

These are code definitions, not verified character outputs for every national layout. Some advanced commands require enabled QMK features or may be unavailable in VIA. Copy a code only after checking your board and host OS.

Community contributions are planned, with OS + language layout + evidence status + admin review. The current public registry is read-only; it does not publish anyone’s private Vault notes or macros.

SOURCES & LIMITATIONS

QMK documents keycodes, not the characters produced under every host layout. Apple and Microsoft document OS shortcuts. Firmware capabilities, national layouts and per-device settings still need actual testing. This prototype stores no user accounts or private macros.
