Selection key

Opens the focused item (for example, a document or folder) in selection +lists and grids.
Selects an option in menus and lists.
Opens the context sensitive Options menu when there is no item to open +and no option to select (see Selection +list).

The Selection key must not directly activate any such function the +user would not expect in the given situation; the Selection key is strictly +a Get-in or Accept key. Therefore, the context sensitive Options menu +will be offered in states where no selectable items exist.

+ + +

Left softkey

Typically labeled Options. Opens the Options menu.

Other +labels and functions:

Select. Used in menu lists and grids where further options are +not available. Selects the focused item; same as the Selection key function.
OK, Yes and other positive replies; used in confirmation +queries.
In the Idle state, a shortcut to a specific application. Configurable +by the user, labeled according to the application.

+ + +

Right softkey

Typically labeled Back. Returns to the previous state.

Other +labels and functions:

Exit in applications' main states.
Cancel. Interrupts a procedure and returns to the previous state; +used in queries and other temporary states.
No and other negative replies; used in confirmation queries.
In the Idle state, a shortcut to a specific application. Configurable +by the user, labeled according to the application.

+ + +

Call creation

Answers the incoming call when the phone rings.
Creates an outgoing call when in Phonebook and other states +where the focus is in a field containing a phone number or a name associated +with a phone number.
Sends a message; used when in a message editor and the To field +contains a valid address.
Functions also as a shortcut for sending files.

During calls:

Puts an active call on hold; activates a held call; swaps active and +held calls, if both exist.
Answers a waiting call (if a call is in progress).

In the Idle state:

Brings up the Last Dialled Calls list for redialing.

+ + +

Call termination

Rejects an incoming call.
Ends an active call.
When there is only a held call, ends the held call.
When there is both an active call and a held call, ends the active +call and activates the held call.
When there are no calls and an application is active, returns to the +Idle state. The application is terminated, except for applications that play +something in the background such as music players or radio. Any unsaved data +is automatically saved (also in case the user has pressed Exit in the Options +menu).

And in devices that have a dedicated power key:

A long press closes down all connections (for example GPRS, data call); +however, this has no effect on IR and Bluetooth

And in devices without a dedicated Power key:

When control is in the Idle state (that is, there are no active calls), +a short press opens the list of Profiles (the Power key menu) and a +long press turns the device OFF regardless of whether there are active packet +data connections in the background or not.
When in the Idle state without any packet data connections active in +the background, a short press opens the Power key menu and a long press +turns the device off.

+ + +

Home / Menu key

Opens the Menu, +allowing application launching and swapping.
When within the Menu, returns to the home screen. +Note that there can be device-specific configurations for Home / Menu key +functionality.
A long press of the Home / Menu key opens the task swapping window, +allowing switching between running applications.

Numeric keypad (0-9, *, #)

Numeric and alphanumeric character entry.
Application-specific shortcuts and other functions.

+ + +

Clear

Clears characters when editing text or numbers.
Deletes documents or other entities in lists and viewers (these functions +always require confirmation from the user).

The Clear key is not used for back stepping or exiting; it is only +used for deletion.

+ + +

Edit (optional)

Opens the Editing menu in editors; the menu contains functions +for input mode changing and other editing functions. See Editing +menu for the contents of the menu.
In editors, can be used together with the Arrow keys to select (highlight) +text, which then enables the Copy and Cut functions.
In markable lists, using the Edit key together with the arrow keys +allows the user to mark several items in the list, then a function can be +executed on all the marked items as one operation.

The Edit key is handled in a special way; the primary action (the Editing menu) +is opened from the key release event, not the key down event as usually. This +is to enable the Mark/Select function where the key is being held down +as a modifier key (see Editing +menu and Lists +and grids for more detailed descriptions of the Select and Mark functions.)

+ + +

Volume keys

Adjust the sound volume during calls and sound playback.
