Шаблон:Refimprove A Help key, found in the shape of a dedicated key explicitly labeled Шаблон:Keypress, or as another key, typically one of the function keys, on a computer keyboard, is a key which, when pressed, produces information on the screen/display to aid the user in their current task, such as using a specific function in an application program.

In the case of a non-dedicated Help key, the location of the key will sometimes vary between different software packages. Most common in computer history, however, is the development of a de facto Help key location for each brand/family of computer, exemplified by the use of F1 on IBM compatible PCs.

Apple keyboards

Шаблон:Quote

On a full-sized Apple keyboard, the help key was labelled simply as Шаблон:Keypress, located to the left of the Шаблон:Keypress. Where IBM compatible PC keyboards had the Шаблон:Keypress, Apple keyboards had the help key instead. As of 2007, new Apple keyboards do not have a help key. In its place, a full-sized Apple keyboard has a Шаблон:Keypress instead. Instead of a mechanical help key, the menu bar for most applications contain a Help menu as a matter of convention.

Commodore and Amiga keyboards

The Commodore 128 had a Шаблон:Keypress key in the second block of top row keys. Amiga keyboards had a Шаблон:Keypress key, labelled as such, above the arrow keys on the keyboard, and next to a Шаблон:Keypress key (where the Шаблон:Keypress cluster is on a standard PC keyboard).

Atari keyboards

The keyboards of the Atari 16- and 32-bit computers had a Шаблон:Keypress key above the arrow keys on the keyboard. Atari 8-bit XL and XE series keyboards had dedicated Шаблон:Keypress keys, but in the group of differently-styled system keys separated from the rest of the keyboard.

Sun Microsystems (Oracle)

Most of the Sun Microsystems keyboards have a dedicate "Шаблон:Keypress" key in the left top corner (left from the "Шаблон:Keypress" key above block of 10 (Шаблон:Keypress) extra keys.[1]
