perkey

Perkey is a term used in multiple disciplines and as a product name. There is no universally accepted definition. The word is formed from the English words per and key, and in many contexts it signals granularity or customization at the level of individual keys.

In computing and software, per-key design describes configurations that apply to each key separately rather than to the input as a whole. This can include per-key macros, per-key remapping, per-key shortcuts, or per-key feedback such as lighting or audio cues in certain interfaces.

In hardware, particularly keyboard devices, per-key functionality is a common selling point. Per-key RGB lighting lets each key display a distinct color, and per-key macro programming assigns unique actions to specific keys, enabling personalized workflows.

As a brand or product name, Perkey or PerKey appears in some product lines associated with keyboards or related peripherals. Because it is used by multiple manufacturers, the term in commerce can refer to different features or offerings without a uniform standard.

In summary, perkey is a context-dependent term most often associated with individual-key customization, whether in software settings, hardware features, or branding.
