Create Key buttons

At run time 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 moves to the left.
  • Move Right moves to the right.
  • Move Up moves up one item in the list.
  • Move Down moves down one item in the list.
  • Page Up moves up one page in the list.
  • Page Down moves down one page in the list.
  • Home moves to the top of the page that’s currently shown.
  • End moves to the bottom of the page that’s currently shown.
  • Backspace moves back to the previously highlighted item.
  • 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.

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.

To create a Key button

  1. In the Graphics Display editor, choose Key from the Objects menu, and then choose the type of Key button to add.
  2. Drag the mouse to position and draw a rectangle the general size and location you want the Key button to be.
  3. Double-click the Key button to open its Properties dialog box.
  4. In the Properties dialog box, specify the how the Key button looks, the caption or image to use on the Key button, and (for Move Up, Move Down, Page Up, and Page Down buttons only) auto repeat.
