SKU CH-CF14-R7JN8

  • All 23 keys freely programmable via dedicated software

Compact One-Handed Macro Keyboard

The Koolertron 23-key mechanical keyboard is built for single-handed operation with red linear switches and blue LED backlighting. All 23 keys are fully programmable through dedicated software, allowing custom macros, shortcuts and lock functions beyond a standard 104-key layout. It targets gamers, editors and programmers who want a dedicated macro pad.

Suited for macro-heavy workflows.

This device suits users who need up to 24 macro slots with delay options and up to 792 stored commands for creative software or gaming shortcuts. Four programmable layers expand the available functions without extra hardware. Buyers who require a complete alphanumeric keyboard for general typing or standard desktop navigation should look elsewhere.

Software setup required; Japanese-market firmware

Installation relies on the supplied programming software to assign keys, macros and backlight levels across the four layers. The interface and documentation are Japanese only and cannot be changed, which may complicate initial configuration for non-Japanese speakers. The unit is designed for 100 V Japanese mains voltage, so a transformer is recommended for use in other regions.

Questions about this item

What operating system and USB port do I need to program the 23 keys with the dedicated software?

A Windows PC with a free USB port is required to run the programming software and assign functions to every key.

Can the 23-key layout sit next to a full 104-key keyboard without key-code conflicts?

Yes, it sends independent key codes so macros and shortcuts on this pad will not interfere with the main keyboard.

How do I confirm the 24 macro slots and 792-command capacity are active after programming?

The blue LED backlight stays lit when the layer is engaged; test each macro in a text editor to verify the full command chain executes.
