7-8 Routing Outgoing Items
Action Button and Picker 7
Users can send items from any application that has an Action button, which
is a picture button that looks like the back of an envelope. To send the
currently selected data item, a user picks a routing action from the Action
picker that pops up when the user taps an Action button. The Action picker
lists all transports capable of sending the currently selected data item, and
it may list other actions provided by the application. Figure 7-4 shows a
sample Action button and picker.

The routing action that a user chooses from an Action picker applies to the
data in the view that contains the Action button. If the view contains multiple
data items that can be individually selected, such as the items listed in an
overview, then the routing action picked by the user applies to the currently
selected items.
If there is nothing to route when a user taps an Action button (for example, if
the user taps the Action button in an overview without first selecting any
items), the system displays a notification alert containing the message
“Nothing is selected.” The warning message does not appear in an application
that defines its own Action-picker items unless the application removes those
items when there is nothing to act on. Your application can include actions
that can function without a target item; in this case your application should
not disable those actions, and the warning message will not appear.
