During debugging, the Apple Event Log window takes on an extra power. The Go To Source menu item in the window’s contextual menu becomes active. This menu item allows a linkage between an entry in the log and the line in the script that generated it:

• Control-click on a log entry and choose Go To Source. The script window comes to the front with the corresponding line highlighted.

Remember also that you can control execution of your script without leaving the Apple Event log window. Menu items (as well as buttons that you can optionally add to the Apple Event Log window’s toolbar) let you issue the Execute and Step commands while the Apple Event Log is frontmost.
