For example, you could assign the F2 key to open a valve when the valve
object has input focus, close a popup display that has focus, and, as a client
key, to open a graphic display containing a process overview.
When a single key has more than one definition, the following rules of
When a graphic display is active and an object has input focus, object
keys have precedence over display keys and client keys.
When a graphic display is active, display keys have precedence over
For example, if you assign the F2 key as a display key in some graphic
displays in an application, and you assign F2 as a client key in the
same application, F2 will only work as a client key if the active display
does not also use F2 as a display key.
When designing an application, pay particular attention to the keys used by
Object keys and display keys generally have precedence over keys used by
embedded objects (for example, ActiveX, or OLE objects).
However, keys used by OLE objects that are not part of FactoryTalk View
(for example, an Excel worksheet), have precedence over object or display
keys. For details, see the pages that follow.
Precedence and the F1 key
When you are developing an application in FactoryTalk View Studio, the F1
key is reserved for opening context-sensitive Help.
At run time, if a graphic display has focus and a press, release, or repeat
action has been defined for the F1 key, F1 acts as a display, object, or client
key instead of opening Help.
Precedence and embedded ActiveX objects
When a graphic display is active and an embedded ActiveX object has input
focus, a key that triggers an action in the embedded object will not trigger
that action, if the same key is also defined as an object or display key.
Instead, when you press the key, the action associated with the object key or
display key will be triggered.
Say, for example, that an ActiveX slider object controls the speed of a motor
by using the F2 key to increase the speed and the F3 key to decrease the
