Fn key
The presence on the keyboard of the
Fn key(short for function). It belongs to modifiers, similar to Shift or Ctrl: by itself it does not perform any action, but when pressed simultaneously with another key, it changes its original purpose. Fn is often found in compact keyboards (see "Format"), but can also be set in full-sized ones. The features it provides include quickly changing the screen brightness or sound volume directly from the keyboard, using the centre keys as a Num-block, launching individual applications, and so on. Specific features of using the Fn key depend on the keyboard model.
Volume control
Volume control methodprovided in the keyboard (if such a possibility is provided at all).
—
Through Fn. Adjustment using the Fn key (see above): increasing and decreasing the volume is carried out by simultaneously pressing Fn and one of the main keys of the keyboard (usually from the F1 — F12 row), The main advantage of this control is that it allows you not to overload the keyboard with additional controls — this, in turn, has a positive effect on the dimensions and cost. The disadvantage is the need to simultaneously press two keys, which is not always convenient.
— Additional keys.
Control with additional keys specially designed for working with volume. A very convenient and practical option: additional keys are usually clearly labeled, while they take up less space and are cheaper than a wheel or a touch slider (see below).
— Wheel.
Control by means of a mechanical wheel, the rotation of which up and down or left and right provides a change in volume. A fairly user-friendly option — visual, intuitive and accessible even blindly. At the same time, the wheel can take up quite a lot of space, and it significantly affects the cost of the keyboard.
— Touch slider. Management using a touch surface, the movement of a finger in one direction or another. The sensor takes up minimal space, looks neat
...and generally fits well with the overall design of the keyboard, but it is not cheap. Therefore, this option is extremely rare, mainly in high-end gaming or multimedia keyboards. Game mode
The presence in the keyboard of a special
game mode.
This function is found exclusively in models of the corresponding specialization (see "Intended use"). Enabling Game Mode disables some of the keys and keyboard shortcuts used by the system, such as the Windows Start menu button and the context menu button. Thanks to this, you do not have to worry that an accidental key press will call a system function and interrupt the game.
In many models, you can customize a specific set of keys that are deactivated in the game mode.
Braided cable
The presence of a braid in the design of a regular keyboard cable.
Braided wire is more durable and reliable than unbraided cable: it is more difficult to damage, it resists sharp bends better. On the other hand, this feature affects the overall cost of the keyboard, and the mentioned advantages do not affect the main functionality of the model. So choosing
a keyboard with a braid makes sense only if you are worried about the reliability of the wire, or if you plan to use it in adverse conditions, with frequent squeezing and bending.
