Notes 
In FileMaker WebDirect, this script trigger will not activate when assigned to a web viewer.
The OnObjectEnter script trigger, OnObjectExit script trigger, and OnObjectKeystroke script trigger can be activated when assigned to summary and calculation fields.
If OnObjectEnter is assigned to a portal object, it will activate whenever a different portal row becomes active. Clicking another object in the same portal row will not cause the portal’s OnObjectEnter script trigger to activate again.
OnObjectEnter will not activate from a portal in Find mode.
When FileMaker Pro switches to Find mode and a field is entered, OnObjectEnter is activated if the trigger is set to run in Find mode.
Scrolling does not make the object active and does not activate this script trigger.
Clicking a button, a popover button, or a panel control does not activate this trigger on the button or tab. Pressing Tab to navigate to a button, tab panel, or slide panel and make it the active object does activate this trigger.
Closing a popover with the Esc key or the Close Popover script step makes the associated popover button active and activates the OnObjectEnter script trigger.
See Actions that don’t activate script triggers for a list of actions that do not activate this script trigger.
