Comparison Logitech MX Keys S vs Logitech MX Keys for Mac

The layout describes the physical geometry of the keys and their standard arrangement: the shape of Enter and Shift, the presence of additional keys, the width of the space bar, and consequently, compatibility with keycap sets and typing familiarity. The standards hardly affect productivity in software and gaming — comfort and how easy it is to find suitable keycaps/cases are more important. The following types are found:

— ANSI (American). A distinctive feature of the American layout is the single-row Enter key; it is the only popular layout where this key occupies one row, not two. Additionally, unlike the European ISO, the Shift keys on ANSI keyboards have the same width, and the Alt key has the same function. The backslash “\” is usually placed above the Enter and can be longer.

— ISO (European). One characteristic feature of the European layout is the Enter key, which occupies two rows and is slightly wider at the top. Also, the modifier keys are asymmetrical: the Shift keys differ in size (the left one is shorter than the right), and the Alts differ in function (the right Alt is marked as “Alt Gr” and is used for typing special characters of European languages). From the similar in many ways "Japanese" JIS layout, the ISO layout differs by the placement of the backslash “\” — it is standardly located near the left Shift (in some models, it is duplicated near the Enter). As a result,...the left Shift is shorter than usual; this can be inconvenient, especially for new users.

— KS (Korean). The “Korean” layout can be distinguished by the characteristic shape of the Enter key: it occupies two rows and is longer at the bottom than at the top. Another feature is the backslash “\”, which is located to the left of the Backspace, resulting in a shorter Backspace than in other layouts.

— JIS (Japanese). A layout much like the European ISO: it has the same two-row Enter with an increased length of the upper half. In many models, the right Alt is labeled “Alt Gr” and is designed for typing special symbols. The main differences lie in two aspects: the length of the left Shift (it is standard in JIS, not shortened) and the placement of the backslash “\” (it is standardly installed to the left of the lower half of the Enter, where some ISO keyboards have a second, additional backslash).

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 Numpad, launching individual applications, and so on. Specific features of using the Fn key depend on the keyboard model.

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.
