I read in help:

"OnRecordLoad
Triggers a script to run after a record is made current or entered, such as after a user or script switches to a layout, switches records, opens a new window, creates or deletes a record, or performs a Find operation."

How do you find this Script trigger, and how do you apply it? My aim is to trigger a script for each record I look through. What do I do, to see it available when I choose Set Script Trigger?
 

In Layout mode, go to Layouts->Layout Setup...->ScriptTriggers, check the appropriate trigger, and select the corresponding script.
