Changing index numbers
Once you have created two or more objects that have index numbers, you can change the
index numbers.
For example, if you have created four input objects, you can modify the fourth object to
have index number 1. However, you cannot change the fourth object to have index
number 5, because there are only four input objects in the display.
When you change an index number, other index numbers are adjusted automatically, so
that no two objects in the display have the same index number, and so that there are no
gaps in the numbering.
If you type an index number that is too high, FactoryTalk View changes it to the highest
available number. If you type a number that is in use, FactoryTalk View renumbers other
objects in the display, changing the tab sequence.
Associating objects and displays with keys
You can associate FactoryTalk View commands with graphic objects in a display, or with
the display itself, using object keys and display keys.
A key can be either a key on a keyboard or keypad, or a button on a touch screen
connected to the computer or monitor an operator is using to interact with an application
at run time.
An operator can use keys to perform actions such as moving from one display to another,
setting tag values, and so on.
Some keys are reserved for use by Windows and FactoryTalk View SE. For more
information about reserved keys, see “Keyboard shortcuts” on page 19-8.
About client keys
Client keys are different from object and display keys. Client keys are always active at run
time. Object and display keys are only active while a specific object or display has focus.
For more information about client keys, see “Creating client keys” on page 24-16. For
information about precedence amongst object, display, and client keys, see page 19-7.
Setting up object keys
Use object keys to connect a graphic object with one or more keys.
For example, if you connect a rectangle to the F4 key, at run time, when the rectangle has
input focus, the operator can press F4 to perform the key’s press, repeat, or release action.
