Keyboard size
75% compact with function row, without number pad
The 75 size is in the model name; the key arrangement is read from the official UK image. Original published inventory: 75% compact with function row and two knobs, without number pad. The shared field describes only the positively established 75% class/function row/no-number-pad arrangement. Knob functions/count and navigation details remain source-specific; 75% does not imply an exact key count or desk span.

Original manufacturer inventory: Wired USB (USB-A to USB-C cable). The exact In the Box passage specifies a 1.8 m detachable cable. Length and detachability are separate facts; the common wired USB inventory does not imply wireless support or a USB data version. This records shared wired USB operation. Exact cable, connector, protocol and detachable-cable facts keep their own source scope; unlisted counterpart details remain unknown and cannot establish a connection-availability difference.
The exact model technical specification names 16.8 million colour key backlighting and a lightbar; the overview identifies the lightbar as front-facing. Per-key backlighting and the front lightbar are recorded separately.
Own-model positive inventory: 75% compact with function row and two knobs, without number pad. The exact source identifies two clickable remappable turn dials. No peer function/material/programmability absence is inferred.
