Create a Key button

At runtime, the operator can use
Key
 buttons to move the cursor and make selections on certain objects. You can use
Key
 buttons with these graphic objects:
  • Alarm list
  • Control list selector
  • Display list selector
  • Trend
  • Audit trail list
These are the types of
Key
 buttons:
  • Move Left
     Key button_move left moves to the left.
  • Move Right
     Key button_move right moves to the right.
  • Move Up
    Key button_move up moves up one item in the list.
  • Move Down
    Key button_move down moves down one item in the list.
  • Page Up
    Key button_page up moves up one page in the list.
  • Page Down
    Key button_page down moves down one page in the list.
  • Home
    Key button_home moves to the top of the page that’s currently shown.
  • End
    Key button_end moves to the bottom of the page that’s currently shown.
  • Backspace
    Key button_backspace moves back to the previously highlighted item.
  • Enter
    Key button_enter selects the currently highlighted item.
You can configure different combinations of
Key
 buttons for different objects. For example, trend objects recognize only
Home
,
End
 and the four
Move
 keys.
Backspace works with the control list selector. If a
Numeric Input Cursor Point
 is selected, the
Backspace
 or
Enter
 key, when clicked or pressed, opens the keypad. To see which objects on your display work with a particular button, open the button's
Properties
 dialog box or
Property Panel
 and click the
Object Browser
 in the
Linked object
 property.
Add and configure each
Key
button separately.
To create a Key button
  1. In the
    Graphics Display
     editor, select
    Objects > Key
     and then the type of button, or drag the object from the toolbox.
  2. Drag the mouse to position and draw a rectangle the general size and location you want the button to be.
  3. Double-click the button to open its
    Properties
     dialog box.
  4. TIP:
    You can set up auto repeat for
    Move Up/Down/Left/Right
    ,
    Page Up
    , and
    Page Down key
     buttons. Set up auto repeat on the
    Timing
     tab.
