Number of buttons
The number of buttons provided in the design of the mouse. However, the term "buttons" can also refer to specific hardware solutions — for example, a solid touch area used in many Apple mice counts as two buttons, because. it is divided into two working areas. But the clickable wheels, as well as the power button, are not taken into account in this calculation.
The minimum number of buttons for modern mice and other similar manipulators is
two : this is the number that is necessary for comfortable work in most modern operating systems. If there are more than two keys, this means that there are additional buttons responsible for specific actions. So, even relatively inexpensive devices can be equipped with
3 – 4 buttons ; in addition to the 2 main buttons, they can have, for example, 2 side thumb keys, or 1 double/triple click button (see below). Solutions for
5 – 6 buttons are extremely popular nowadays; among them are many gaming mice, where the mentioned thumb buttons are supplemented with a double / triple click, a sniper button and/or a DPI switch (see also below about these functions). And in the most multifunctional models,
7 – 8 buttons and even
more can be installed. In some cases, this number exceeds a dozen and a half; such mice are usually gaming devices designed for RPGs and other simil
...ar genres where it is important to have a wide range of actions at your fingertips.4D wheel
The presence
in the mouse of 4D-wheels — wheels with the function of navigating in four directions. In other words, such equipment allows you to scroll the image on the screen not only up and down, but also left and right. The specific implementation of this function may be different: in some models for horizontal navigation, the wheel can tilt to the sides, in others, switching between horizontal and vertical scrolling is carried out using a separate button. However, anyway, this feature expands the functionality of the mouse, while the 4D wheel is cheaper and takes up less space than two separate wheels (see "Number of scroll wheels").
Inertial wheel
A wheel with an accelerated scrolling mode that allows you to scroll through a large “sheet” of pages in text documents, spreadsheets or on Internet resources in just one movement.
The inertial wheel is a hallmark of a number of Logitech mouse models.
Programmable buttons
The presence
of programmable buttons in the design of the mouse. In this case, the buttons mean not only the keys, but also the scroll wheels, which are usually able to work on pressure.
Almost all models with this feature are gaming (see "By Direction"). Usually, programming is carried out using special proprietary software, while the functionality of such a setting may be different. For example, in some models, only one action can be tied to one button, in others — a whole series of actions (such as a combination of attacks in an RPG). Often, it is possible to configure one button for different actions in different games.
However, this feature provides an additional convenience: the mouse keys are right at hand, and it is usually easier (and faster) to use them than to reach for the button (s) on the keyboard.
Battery time
The operating time of the mouse powered by replaceable elements (see "Power") on one set of batteries.
The operating time in this case is quite approximate: it is indicated for a certain average mode of use. The actual battery life may turn out to be either less or more than the claimed one, depending on the specifics of the application; in addition, the quality of a particular brand of batteries greatly affects the operating time. Nevertheless, this is a fairly reliable indicator, it is quite possible to evaluate different models and compare them with each other: the difference in the claimed operating time is usually quite consistent with the difference in real battery life when using batteries of similar quality.
It is worth saying that modern battery-powered mice have pretty solid battery life, measured in months; in the most "long-playing" models, the operating time is about 36 months (that is, 3 years).
Weight
The total weight of the mouse. For models with a wired connection, usually, it is indicated without cable, and for devices with weight adjustment (see above) — without weights.
This parameter is important primarily for professional gaming applications, although it is often relevant for ordinary users. Theoretically, less weight promotes speed and reduces fatigue. At the same time, in fact, much depends on the personal habits and preferences of the user: a mouse that is too light may “not be felt in the hands” and not give familiar feedback. Therefore, although most mice have a lower weight limit of
60 – 80 g, however, even among professional gaming models there are much more massive devices —
120 – 140 g or
more. The lightest variety of "rodents" is laptop (see "In the direction"), among them devices come across and
less than 60 g.
Also note that the weight to some extent depends on the size and “tricked out” of the device, but there is no unambiguous dependence here: models similar in size and functionality can differ markedly in weight.
