Break on Errors (Alt+D,E)
■ Causes your project to stop at the first statement in the
  most recently executed error-handling subroutine. This
  suspends project execution so you can locate the source
  of the error.
 
■ Tip: Use this command only when debugging a project that
       contains an error-handling procedure.
 
■ A bullet (•) appears next to the command name on the Debug
  menu when the toggle is on.

  └──────────────────┘
 
■ Turning on Break on Errors also enables the History On
  toggle, so that the 20 statements executed just before the
  breakpoint are also recorded. Use Shift+F8 once to back up
  to the statement that caused the error. Backing up further
  displays the statements that led to the error.
