Anti-Ghosting
Technology aimed at neutralizing phantom button presses in keyboards with gaming ambitions. The function allows you to simultaneously press numerous keys without false positives of adjacent buttons — a similar situation often occurs in membrane keyboards due to their design features.
#KRO
A parameter that determines the maximum number of simultaneously pressed keys, the signal from which the keyboard is able to process and transmit to the computer. Instead of the "lattice" symbol in the abbreviation KRO, a number is indicated showing the allowable number of simultaneously pressed buttons. Most membrane keyboards come in the 2KRO and 3KRO grades, mechanical models usually start at 6KRO. The NKRO marking says that it is possible to issue a signal from an unlimited number of keys in one sitting.
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.
Metal structure
Keyboards whose body or certain elements are made of metal. This can be either the entire body or its parts - for example, a metal plate as a base for keys. Note that when it comes to the metal construction of the keyboard, the latter option is more common.
Compared to plastic—the most common keyboard case material—metal is much stronger, more durable, and more durable. It has a significant weight, but in this case it can also be written down as advantages — massiveness contributes to stability and reduces the likelihood that the keyboard will "fidget" under the fingers. In addition,
metal cases look stylish and solid. On the other hand, they are noticeably more expensive than plastic ones, and the advantages mentioned are not so much practical as psychological. Therefore, this feature is found mainly in advanced
gaming models (see "By Direction"), for which a solid appearance is no less important than functionality.
Replacement keys included
The presence of interchangeable keys — more precisely, caps for keys ("keycaps") — is included in the package of the keyboard.
This feature is found mainly in
gaming keyboards(see "By Direction"). Replaceable in them are usually made only individual keys, the most significant in games — in particular, WASD and arrows. For such keys, two sets of keycaps are provided — ordinary ones, in tune with the rest of the buttons, and gaming ones that stand out from the general background. Thanks to this, you can adjust the keyboard to the current format of use: for example, in games, the keys that stand out by colour are very convenient, and when typing, they can be confusing.
