What is that Fn key on the keyboard?

FN is the abbreviation of the word function, almost all laptops have this FN key, and its function is to form a key combination with other keys to achieve control.

The fn key is a key combination that is not useful on its own and needs to be combined with other function keys to quickly change the operating characteristics, and the keys it can combine are marked in blue on the keyboard.

The fn key on the notebook keyboard is generally located in the lower left corner of the keyboard, it needs to be used together with other keys, using fn with other keys can be used to adjust the brightness of the notebook screen, the sound level, turn off the screen display, disable the trackpad, turn on and off the wireless network ......and other functions.

These buttons can be used with the FN key to adjust the brightness of the screen, the sound volume and other functions. The following figure is an example, let's demonstrate a few operations, and you can fully understand the role of the fn key.

Look at the top row of keys in the keyboard in the picture above, count the 7th and 8th from the left, they all draw a small horn pattern on them, we now hold down the fn key in the lower left corner of the keyboard with one hand and don't let go (the bottom row, the second on the left), and then press the button with a small speaker, keep pressing, then you will find that your screen brightness is gradually brightening or darkening. I won't introduce the other features one by one, you can try them yourself.

Tips for using the fn key on your keyboardPay attention not to confuse the fn key with the f1-f12 key when adjusting the brightness and volume of the screen, press and hold the fn key while pressing other keys, you can achieve some other functions, adjust the screen brightness and sound, and achieve some **functions, such as**pause the next song and other functions。

Some laptops.

There is a fnlock key in it, press fn+fnlock to cancel the fn key combination function, but the fnlock button is set in different positions in different notebooks, for some notebooks, such as the Shenzhou series of notebooks are not fnlock buttons, and they can't lock the fn key function.

The FN function key (FN is an abbreviation for function) is a modifier key used on many computer keyboards, commonly found in Apple standard keyboards, multi** keyboards, and some laptop keyboards. So the fn key on the keyboard is in **? Let's take a look at the answers.

1. The fn key, not every keyboard has it. Only some notebooks and some Bluetooth keyboards paired with notebooks have the FN key. The picture below shows a normal keyboard, which does not have an FN key.

2. This is a notebook keyboard, and its fn key is in the bottom left corner.

3. The function of the fn key is to hold down the fn key to make the top part of the key can be used as the second function.

The above is an introduction to the content of the fn key on the keyboard.

The fn key is a function key, which is a key that appears in the lower left corner of notebook and netbook keyboards. It means "function".

It is used to form a key combination with other keys to achieve control. These key combinations can be used to adjust the hardware (hibernation, switch displays) or to supplement the implementation of buttons that are present on desktops but omitted on laptops.

The fn key is mostly a key on a notebook, and it can be used to form a key combination with the F1 12 key. to make up for the lack of a laptop number of keys.

Key combination of fn key:FN+F2: Turn on and disconnect the signal of the wireless network card.

FN+F3: Display switching.

fn+f6: Mute Unmute.

FN+F8: Increase the brightness of the screen.

FN+F9: Reduce the brightness of the screen.

fn+scrlk: Equal to pressing the break key.

fn+insert: is equal to pressing the print screen key.

fn+del: is equal to pressing the pause key.

FN is a modifier key that can be used in the same way as other modifiers (e.g. Control, Shift, Altgr, Altgr, Option, Command). In the case of standard modifier keys, the microcontroller within the keyboard emits the scancode of the modifier key itself, which is then interpreted by the operating system and combined with other keys.

The fn key is a type of meta-modifier key, when it is pressed in combination with other keys, the operating system will see the modified scan code, which allows the keyboard to directly emulate a full-size keyboard, so that the operating system can use the standard keymap designed for full-size keyboards, but because of this, the operating system does not have the concept of the fn key, so the key cannot be mapped properly in the software.

While the fn key is most commonly handled in the keyboard's microcontroller, the computer will have no way of knowing whether the fn key has been pressed or not. For example, some manufacturers such as Lenovo Group handle this mapping in the BIOS running the main CPU, allowing the interrupt processor of the BIOS to modify the mapping of the FN key; In Apple's product design, pressing the FN key twice triggers the dictation function.

In addition to mapping to standard scroll lock and number lock keys, the FN key combination can also be mapped to control system interfaces, commonly used to change screen brightness, VGA output, and speaker volume on laptops.

It means "function" and is used to form a key combination with other keys to achieve control.

It is a key that appears more and creeps in the lower left corner of notebook and netbook keyboards. Some laptops have the control key in the bottom left corner, and the fn is in the bottom row of the keyboard from the second from the left. "FN" is mostly marked with marking, but there are also green and purple keys, and the functions achieved by combining them with the same color are indicated on the other key.

These key combinations can be used to adjust the hardware (hibernation, switch displays) or to supplement the keys that are available on desktops and omitted from notebooks.
