Help key
Template:Short description Template:Refimprove A Help key, found in the shape of a dedicated key explicitly labeled Script error: No such module "key"., 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
On a full-sized Apple keyboard, the help key was labelled simply as Script error: No such module "key"., located to the left of the Script error: No such module "key".. Where IBM compatible PC keyboards had the Script error: No such module "key"., 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 Script error: No such module "key". 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 Script error: No such module "key". key in the second block of top row keys. Amiga keyboards had a Script error: No such module "key". key, labelled as such, above the arrow keys on the keyboard, and next to a Script error: No such module "key". key (where the Script error: No such module "key". cluster is on a standard PC keyboard).
Atari keyboards
The keyboards of the Atari 16- and 32-bit computers had a Script error: No such module "key". key above the arrow keys on the keyboard. Atari 8-bit XL and XE series keyboards had dedicated Script error: No such module "key". 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 dedicated "Script error: No such module "key"." key in the left top corner (left from the "Script error: No such module "key"." key above block of 10 (Script error: No such module "key".) extra keys.[1]
