Additional keys

The number of additional keys provided in the design of the keyboard.

Such keys do not belong to the standard layout and are intended for quick access to specific functions or individual applications — for example, to control the media player or open mail with one click. This function is convenient because commands from additional keys are usually recognized by the system regardless of what is on the screen — thanks to this, for example, you do not have to close the text editor to switch tracks in the player.

Note that in this case we are talking about individual keys that have a strictly defined purpose and corresponding markings. Programmable buttons, the Fn key (see below) and the functions of the main keys implemented through Fn are not taken into account in this paragraph.

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.

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.

Cyrillic colour

The colour of the Cyrillic letters printed on the keyboard.

This colour is usually chosen so that the letters are clearly visible. This point does not affect the functionality of the keyboard, and the choice in this case depends mainly on personal preferences. However, there is also a practical point: for inexperienced users who have not mastered touch typing, it is desirable that the letters stand out as much as possible against the background of the keys.

Transparent letters are a separate case — they are used in keyboards equipped with a backlight (see below), due to which such characters, when the backlight is on, are visible even in the dark.

Skeleton keyboard

Keyboards made in a Skeleton case.

The main difference between such cases and the classical ones is that the mechanism of each key is not hidden at the base of the keyboard, but, on the contrary, rises somewhat above it. Due to this, the keys can be easily removed and put back into place, which makes it much easier to clean from dust and dirt. And in gaming keyboards of this type, the kit often includes interchangeable buttons that differ in colour and texture from the main ones. Actually, almost all models with this feature are specifically gaming (see "By Direction").
