Compact macro controller

The Ruth's sister 3 Keys 1 Knob macro keyboard adds a small, dedicated control surface to a tablet or desktop setup. Three programmable keys and a rotary encoder handle media, shortcuts or custom macros through a single USB connection. Red linear switches provide smooth, quiet actuation without tactile feedback.

Three keys and one knob

The layout covers frequent commands such as volume, track skip, mute or application-specific shortcuts, leaving the main keyboard free for typing. Only three discrete inputs and one encoder are available, so workflows needing large macro banks or extensive jog-shuttle control will require a larger device.

Highlights

  • 3 programmable keys and a rotary knob streamline macros and media control
  • Red linear switches deliver smooth, consistent keystrokes without tactile bump
  • Per-key RGB lighting lets you match colours to your setup
  • Compact design fits tablets and desktops for portable productivity

Questions about this item

Will the red mechanical switches feel consistent with the switches on my existing mechanical keyboard?

The unit uses red linear switches; if your current keyboard also uses red linear switches the actuation force and travel will match closely.

How can I confirm the RGB lighting and knob are functioning correctly after I connect it?

Plug the internal power cable into a USB header; all three keys, the knob and the per-key RGB should light and respond immediately in the configuration software.
