Selected alarm indicator | Select whether the selected alarms will be indicated by a highlight bar or by a cursor.
Word wrap | Select this check box if you want the text to continue on the next line at the beginning of a new word. If this check box is cleared, the text continues on the next line whenever the maximum text length is reached, even if this occurs in the middle of a word or number. The maximum text length depends on the width of the object and the font size.
Filtering | Filter the object to show only the alarms from the specified triggers.
Filtered triggers | Click the Browse button to open the Trigger Label Selector, where you can select the alarm trigger labels whose alarms will be included on the display as they occur. If this box is blank, all alarms are shown.
