Programmable keys
The number of programmable keys provided in the design of the keyboard. Like the additional ones described above, such keys are located outside the standard layout. At the same time, they do not have a rigidly defined purpose — each individual function can be set by the user himself, hence the name. Some manufacturers, however, can initially programme these keys, but this programme can still be changed if desired.
The advantage of such equipment is obvious: additional features of the keyboard can be easily customized. Gamers especially appreciate this feature, so
programmable keys are often found in gaming models. On the other hand, the keys themselves usually have neutral markings (for example, P1, P2 ...), and the user has to remember which function is “linked” to where; this can cause confusion.
Lighting
The colour of the backlight provided in the design of the keyboard.
In general, the
backlight performs two functions: practical (makes the keys more visible in low light) and aesthetic (gives the keyboard a beautiful appearance). However, it cannot be said that
non-backlit keyboards will be unusable in the dark, the light from the monitor will still illuminate the buttons. The simplest version of the backlight is one-colour. In this case, specific colours can be different: for example,
white is well suited for general-purpose keyboards (work or home), but other shades can be found in gaming or design models, for example,
red,
green,
blue,
purple or
orange. If two or three colours are indicated for the keyboard, this may mean either the ability to switch between these colours, or that this model comes in several versions that differ in the shade of the backlight; these nuances should be clarified separately.
The most advanced options are
multi-colour and
RGB backlighting. Multi-colour systems are called systems in which more than three colour options are provided, sometimes with intermediate shades. And RGB-backlight all
...ows you to choose almost any shade at the request of the user; in addition, the possibility of synchronization (see "Illumination with effects") is found mainly in such systems, although single-colour keyboards can also be equipped with other effects.Lighting effects
The presence of additional effects in the backlight provided in the keyboard (see above). For models with the
backlight synchronization function, this item indicates the synchronization technology.
Additional backlight effects can be different: multi-coloured backlighting of individual keyboard zones, smooth “flowing” of one colour into another, response to system or game events, etc.; specific features should be clarified for each model separately. As for synchronization, it allows you to coordinate the backlighting of various system components — keyboards, case mice, graphics cards, etc.; this opportunity is especially appreciated by the owners of high-end gaming stations. Coordination requires that all highlighted components support the same technology; usually, each manufacturer has its own — Aura Sync for Asus, RGB Fusion for Gigabyte, etc.
