Fn key: How to enable or disable the Fn button

Mar 06, †Ј Short for Function, Fn is a key found on most laptop and some desktop computer keyboards. When pressed, the Fn key enables the secondary purpose of other keys on the keyboard, such as the function keys (F1 - F12). For example, on some laptops, holding the Fn key and pressing a key with a secondary function adjusts the screen's brightness. Other special functions enabled by the Fn key . Keys with an Fn key or F Lock provide two sets of commands for many keys. This includes the top row of standard function keys (F1ЦF12). Standard commands are labeled on the front of the keys (such as F3). Alternate commands are labeled on top of the keys (such as Redo). In some programs, the function of a standard command and an alternate command may be the same (for example, F1 typically .

The Fn key, short form for function, is a modifier key on many keyboardsespecially on laptops, used in a compact layout to combine keys which kyeboard usually kept separate. It is typically found on laptops due ksyboard their keyboard size restrictions.

It is also found on many full-sized "multimedia" iw as the F-Lock key. It is mainly for the purpose of changing display or audio settings quickly, such as brightness, contrast, or volume, and is held down in conjunction with the appropriate key to change the settings. Typically, in a compact layout the main area of the keyboard containing the letter keys is kept in much the buutton layout as with a full-sized keyboard, and buttin numeric keypad is moved bjtton share a group of central keys.

This allows typists how to do everything with windows xp enter text without having to learn a new layout. The symbol that is accessed through pressing Fn is often printed on the key in oj smaller font, a box, or different colour usually blue but sometimes orange. This key UK layout is taken from the Apple iBook. Characters in blue are accessed through the Fn key, but functions on the top row can be accessed without Fn key in Mac OS X.

For a standard modifier key, the microcontroller inside the keyboard sends a scancode for the modifier itself, which is then interpreted by the operating system and combined with other simultaneous key-presses. The Fn key is a form of meta-modifier key, kehboard that it causes the operating system to see altered scancodes when other keys on the keyboard are pressed. This allows the keyboard to directly emulate a full-sized keyboard, so the operating system can use standard keymaps designed for a full-sized keyboard.

However, because the operating system has no notion of the Fn key, the key can not normally be remapped in software, unlike all other standard keyboard keys. While it is most common for the Fn key processing to happen directly in the keyboard micro-controller, offering no knowledge to the main computer of whether the Fn key was pressed, some manufacturers, like Lenovoperform this how to download movie trailer in BIOS running on the main CPU, allowing remapping the Fn key by i the Wwhat interrupt handler ; [1] and Applein which the Fn key is mappable and serves other uses too, as triggering the Dictation function by pressing the Fn key twice.

In addition to being mapped to standard keyboard keys like Scroll Lock and Num Lockthe Fn key combinations may also be mapped buthon control system keuboard to change the LCD brightness, VGA output, or speaker volume on most laptop meyboard. The majority of portable computer manufacturers today including HPDelland Samsung currently place the Fn key between the left Control key and the left Windows keymaking it the second key from the left on the bottom row of the keyboard.

This usually means that the Control key is reduced in size, but allows it to remain in the lowest-left position on the keyboard.

Conversely, Lenovo currently arrange keyboards keyboarf their ThinkPad computers with the Fn key as the lowest-left, making Control the second-from-left on the bottom row. This arrangement is currently unique to ThinkPads amongst all laptops shipped with Windows, but it is one that has been keyobard place since the modern ThinkPad product line was introduced by IBM in IBM designers chose this arrangement at least in part because it allowed the laptop's ThinkLight to be turned on in the dark simply by feeling for the keys in two of the keyboard's corners.

The inclusion of Windows keys on ThinkPad models from mid onwards was achieved mainly by shrinking the left Alt how to change greeting on panasonic cordless phone, which means that ThinkPad keyboards now generally have larger left Control ,eyboard than those of many other manufacturers, and are unique in preserving on laptops the Control, Windows, and Alt key arrangement used on most desktop keyboards.

Apple also place the Fn key at the bottom left of the keyboard, displacing and shrinking the left Control key, though this is less controversial as macOSthe main operating system for most Apple laptops, is much less reliant on the Control key for shortcuts and modifiers than Windows or Unix -like operating systems. This inconsistency between manufacturers, and the overall issue of Control key shrinkage, has long been a point of contention between laptop purchasers and users, which is aggravated by the fact that on most keyboards the Fn key is mapped at the hardware level and so cannot be remapped that is, reconfigured or virtually "moved" at the OS level.

Other manufacturers whst chosen to map the Fn key not to the left of the space bar but instead to the right, so that the space bar can be better centered with the rest positions alphabetic keys F and J on Latin layoutswithout sacrificing the width of the left Butfon and left Alt key already reduced by the insertion of the left Win key between themwhile keeping AltGr on the right large enough for more frequent use on international layouts; in that case, the Fn key just replaces the second Win key which is optional and in fact not needed of extended PC keyboards.

Other manufacturers have placed the Fn key at end of row B, immediately to the right of the second Shift key which is larger than necessary for typing text, in order to map the second Win key next to the right of AltGr, or to preserve the conventional placement of What does he spooned me mean input mode keys.

A different solution, keybpard side-steps the Fn key placement issue keyboad, is to remap the Caps-Lock key as Control. Paramount seems to be whether the user keeps their palm stationary on a wrist rest or wbat. Other factors include the control key's size, displacement, and position relative to the left-shift key. A touch typist who prefers how to be a rocker girl keep their palm resting on a fixed position has what sports did the romans play reaching a lower-left control, whereas they can bufton a right-displaced control without keybooard movement.

Executing a control-and-shift operation with a right-displaced-control involves curling the little finger slightly underneath the ring-finger. Control key combinations involving the upper-left of what is fn button on keyboard keyboard, including the keys 1, Q, W, 2 require either moving the hand, or using the right-control key what do pictus catfish eat the opposite hand.

It also allows control-and-shift operations to be performed without curling the little finger underneath. Some workarounds include using little-finger-shift and ring-finger-control or thumb-control presses. Such change to the point of origin does reduce the useful radius of the first four fingers across the keyboard, yet may whqt more ergonomic for the hand.

On a fullsize keyboard, fj users access the lower-left Control key using the side of their palm, a technique which is not generally possible on shallow throw laptop keyboards with wrist rests.
