End Key
The key is a key commonly found on desktop and laptop keyboards. The key has the opposite effect of the Home key. In some limited-size keyboards where the key is missing the same functionality can be reached via the key combination of or Control + End keys Its standard symbol as described in ISO/IEC 9995-7, i.e. , is used on some full-size keyboards instead of a possibly localized text label. Microsoft Windows In modern Microsoft Windows text editing applications, the key is primarily used to move the cursor to the end of the line in which it is positioned. When the text is not editable, it is used to scroll to the end of the document; this can also be done in editable text if the key is pressed along with . The key can also be used to highlight all the characters after the cursor in a certain line if pressed along with in editable text. macOS In most macOS applications, the key works differently than on other platforms.

Control Key
In computing, a Control key is a modifier key which, when pressed in conjunction with another key, performs a special operation (for example, ). Similarly to the Shift key, the Control key rarely performs any function when pressed by itself. The Control key is located on or near the bottom left side of most keyboards (in accordance with the international standard ISO/IEC 9995-2), with many featuring an additional one at the bottom right. On keyboards that use English abbreviations for key labeling, it is usually labeled ( or are sometimes used, but it is uncommon). Abbreviations in the language of the keyboard layout also are in use, e.g., the German keyboard layout uses () as required by the German standard DIN 2137:2012-06. There is a standardized keyboard symbol (to be used when Latin lettering is not preferred). This symbol is encoded in Unicode as U+2388 , but it is very rarely used.

Text-based User Interface
In computing, text-based user interfaces (TUI) (alternately terminal user interfaces, to reflect a dependence upon the properties of computer terminals and not just text), is a retronym describing a type of user interface (UI) common as an early form of human–computer interaction, before the advent of bitmapped displays and modern conventional graphical user interfaces (GUIs). Like modern GUIs, they can use the entire Electronic visual display, screen area and may accept computer mouse, mouse and other inputs. They may also use color and often structure the display using box-drawing characters such as ┌ and ╣. The modern context of use is usually a terminal emulator. Types of text terminals From console application, text application's point of view, a text screen (and communications with it) can belong to one of three types (here ordered in order of decreasing accessibility): # A genuine text mode display, controlled by a video adapter or the central processor itself. ...

Linux
Linux ( ) is a family of open source Unix-like operating systems based on the Linux kernel, an kernel (operating system), operating system kernel first released on September 17, 1991, by Linus Torvalds. Linux is typically package manager, packaged as a Linux distribution (distro), which includes the kernel and supporting system software and library (computing), libraries—most of which are provided by third parties—to create a complete operating system, designed as a clone of Unix and released under the copyleft GPL license. List of Linux distributions, Thousands of Linux distributions exist, many based directly or indirectly on other distributions; popular Linux distributions include Debian, Fedora Linux, Linux Mint, Arch Linux, and Ubuntu, while commercial distributions include Red Hat Enterprise Linux, SUSE Linux Enterprise, and ChromeOS. Linux distributions are frequently used in server platforms. Many Linux distributions use the word "Linux" in their name, but the Free ...

Command Key
The Command key (sometimes abbreviated as Cmd key), , formerly also known as the Apple key or open Apple key, is a modifier key present on Apple keyboards. The Command key's purpose is to allow the user to enter keyboard commands in applications and in the system. An "extended" Macintosh keyboard—the most common type—has two command keys, one on each side of the space bar; some compact keyboards have one only on the left. The symbol (the " looped square") was chosen by Susan Kare after Steve Jobs decided that the use of the Apple logo in the menu system (where the keyboard shortcuts are displayed) would be an over-use of the logo. Apple's adaptation of the symbol—encoded in Unicode at U+2318—was derived in part from its use in Nordic countries as an indicator of cultural locations and places of interest. The symbol is known by various other names, including "Saint John's Arms" and " Bowen knot". History Apple's computers up through the 1979 Apple II Plus did ...

Option Key
The Option key, , is a modifier key present on Apple keyboards. It is located between the Control key and the Command key on a typical Mac keyboard. There are two Option keys on modern (as of 2020) Mac desktop and notebook keyboards, one on each side of the space bar. (As of 2005, some laptops had only one, in order to make room for the arrow keys.) Apple Inc., Apple commonly uses the symbol to represent the Option key. From 1980 to 1984, on the Apple II, this key was known as the closed apple key or the solid apple key, and had a black line drawing of a filled-in on it. Since the 1990s, "Alt" has sometimes appeared on the key as well, for use as an Alt key with non-Mac software, such as Unix and Windows programs; as of 2017, the newest Apple keyboards such as the Magic Keyboard (Mac), Magic Keyboard no longer include the "Alt" label. The Option key in a Mac operating system functions differently from the Alt key under other Unix-like systems or Microsoft Windows. It is not us ...

Shift Key
The Shift key is a modifier key on a alphanumeric keyboard, keyboard, used to type majuscule, capital letters and other alternate "upper" characters. There are typically two Shift keys, on the left and right sides of the row below the home row. The Shift key's name originated from the typewriter, where one had to press and hold the button to shift up the case stamp to change to capital letters; the Shift key was first used in the E. Remington and Sons, Remington No. 2 Type-Writer of 1878; the No. 1 model was capital-only. On the Keyboard layout#QWERTY, US layout and similar keyboard layouts, characters that typically require the use of the Shift key include the bracket, parentheses, the question mark, the exclamation point, and the colon (punctuation), colon. When the Caps Lock key is engaged, the Shift key may be used to type lowercase letters on many operating systems, though not on macOS or on Microsoft Windows keyboard layouts that have the SGCAPS feature.

Arrow Keys
Arrow keys or cursor movement keys are keys on a computer keyboard that are either programmed or designated to move the cursor (computers), cursor in a specified direction. The term "cursor movement key" is distinct from "arrow key" in that the former term may refer to any of various keys on a computer keyboard designated for cursor movement, whereas "arrow keys" generally refers to one of four specific keys, typically marked with arrows. Arrow keys are typically located at the bottom of the keyboard to the left side of the numeric keypad, usually arranged in an inverted-T layout but also found in diamond shapes and linear shapes. Arrow keys are commonly used for navigating around documents and for playing games. The inverted-T layout was popularized by the Digital Equipment Corporation LK201 keyboard from 1982. Historical development Before the computer mouse was widespread, arrow keys were the primary way of moving a cursor on screen. Mouse keys is a feature that allows c ...
