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.

Palm rest

The presence of an additional palm rest in the design of the keyboard. Such a stand is located in the lower (closest to the user) part of the device and is a kind of continuation of the “board”, providing additional support and increasing the comfort of use. However, comfort is largely a matter of personal preference, and not all users like stands; therefore, most often they are made removable.

Waterproof

Protecting the keyboard from spilling liquid on it. Most waterproof keyboards do not have a full-fledged sealed case and are designed to remain operational in the event of accidental contact with a relatively small amount of liquid (up to 200 mL) — for example, in the classic case of spilling coffee on the keyboard.

Number of buttons

The number of buttons in the design of the mouse, which is included in the kit. The minimum number of such buttons to work in most modern operating systems is two, and a larger number, usually, means that the mouse has additional functions. For example, the third key can be used to change the resolution of the mouse sensor on the fly, for the function of double or triple click (the latter is used in games for shooting in short bursts); a pair of buttons on the side under the thumb is usually configured for the "back" and "forward" functions in the browser, etc. And in gaming mice, there can be more than a dozen additional buttons for the fastest access to various game functions.

Sensor resolution

Resolution of the optical sensor used in the bundled mouse. Like a camera matrix, such a sensor consists of many individual photosensitive points; this parameter indicates how many sensor points are for each inch of the surface on which the mouse moves.

Although high DPI values \u200b\u200bare often considered an indicator of good mouse accuracy, in fact this moment only affects the speed of moving the cursor around the screen (and not the actual one, but the maximum possible one — the “working” DPI value in the settings is often reduced, otherwise using the mouse would be inconvenient ). Therefore, high sensor resolutions are important mainly for working on large monitors, and even in such cases, indicators of 1000 – 3000 DPI are considered quite sufficient, higher values \u200b\u200bare more of a publicity stunt than a really justified necessity.
