Key profile
The distance that the key travels when pressed — from the initial position to touching the contacts and sending the "command". Indicated as
high or low.
Keyboards with low key travel(3 mm or less) are considered to be more comfortable for fast input (such as fast typing). However, the best option largely depends on the habits and preferences of a particular user.
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.
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").
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.
