elisp: Debugger

 
 17.1 The Lisp Debugger
 ======================
 
 The ordinary “Lisp debugger” provides the ability to suspend evaluation
 of a form.  While evaluation is suspended (a state that is commonly
 known as a “break”), you may examine the run time stack, examine the
 values of local or global variables, or change those values.  Since a
 break is a recursive edit, all the usual editing facilities of Emacs are
 available; you can even run programs that will enter the debugger
 recursively.  Recursive Editing.
