Keyboards with an external separate Num-module

Num module

— a set where a separate numeric keypad in the same style and with the same switches is added to a compact 75/65/60% keyboard: in everyday work, you keep the "short" keyboard and mouse closer to the center, and for Excel, 1C, accounting, or CAD, you place the Num-pad on the right or left, turning it if desired into a macro pad for editing and gaming; connection is usually shared via a single 2.4 GHz dongle or Bluetooth, wired USB-C is also common, many modules have battery, backlighting, and even encoder; compared to the 100%/96% format, this set is more flexible and saves space, but the nuances are possible "non-standard" keycap sizes and the need to charge the second device.
