Documentation
Abnormal hook used to jump to the source code for the current frame.
Each hook function is called with no argument, and should return non-nil if it is able to switch to the buffer containing the source code. Execution of the hook will stop if one of the functions returns non-nil. When adding a function to this hook, you should also set the :source-available flag for the backtrace frames where the source code location is known.
