Glyph Scripts

Firmware protocol v9+expanded script set in v10

A glyph script is a purely cosmetic override that redraws the letter and digit legends on the keycaps in an alternative script, while leaving everything else — app overlays, the language layer, shortcut hints — exactly as it was. It changes the look of the keycaps without changing what the keys actually type.

Available scripts

Script	Notes
Standard	Normal legends (the default — glyph script off).
Tengwar	Elvish-style feanorian script. Caseless.
Runes	Elder Futhark runic.
Aurebesh	Blocky sci-fi alphabet.
Standard Galactic	The “commander” alien alphabet.
Cirth	Angerthas-style runes.
IBM VGA	CP437 / DOS text-mode look.
Commodore 64 (screen)	The C64’s built-in screen font, as it appeared on the monitor.
Amiga	Workbench / Topaz look.
APL	The APL symbol set.
Braille	Braille cell patterns.
Commodore 64 (keycap)	The narrow capitals printed on the C64’s own keys. Each letter key also shows its two PETSCII graphics below the letter, as on the front of a real C64 key: Commodore + key on the left, Shift + key on the right. They are drawn only; the key still types the letter.

Note

The scripts that have their own numerals (Tengwar, C64, …) also restyle the digit row; the others leave numbers as normal. A key whose glyph the chosen script can’t draw simply keeps its normal legend — so the board never shows a blank key.

Selecting a script

• On the keyboard — a key on the settings layer, under More…. Like the idle-style key it names the active value — SCRIPT: over the current script — and each tap moves to the next one, and after the last one it returns to Standard.
• Tray menu — right-click the PolyKybdHost tray icon → Keycap Script → pick a script (or Standard to turn it off).
• Command line — polyctl glyph-script tengwar (or standard, runes, c64, c64keys, braille, …).

Your choice is saved on the keyboard and persists across reboots.

Requirements

Glyph scripts are drawn from a fantasy font-pack bundle that PolyKybdHost flashes to the keyboard automatically the first time it connects (see Font Packs & Resources). Until that bundle is present the override falls back to the normal Latin legends, so nothing breaks if it hasn’t been flashed yet.

To make the normal legends bigger instead of changing their style, use a separate setting: see Legend Size.
