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, OS hints — exactly as it was. It’s a fun way to theme the board 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	The C64 ROM font.
Amiga	Workbench / Topaz look.
APL	The APL symbol set.
Braille	Braille cell patterns.

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

• Tray menu — right-click the PolyKybdHost tray icon → Keycap Script → pick a script (or Standard to turn it off). There’s also a Reset glyph script to Standard button in the Settings dialog.
• Command line — polyctl glyph-script tengwar (or standard, runes, 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.

Tip

Newer firmware accepts more scripts than an older keyboard may have fonts for — an unknown script just renders the normal legend. So the script list can grow without a firmware-protocol change; a keyboard that lacks a given font degrades gracefully.
