Select the Listener tab of the Stepper tool to display a Listener.
This area offers all the usual Listener and Debugger commands. Moreover, the execution environment is that of the function currently being stepped, and contains the variables of each frame on the stack.
The Stepper listener also offers the following listener commands to control stepping.
Step To Call At the start of a form, steps to the function call of that form after evaluation of the arguments. At a function call or at the end of a form, steps to the function call of the enclosing form.
Step To Value At the start or function call of a form, steps to the value of that form. At the end of a form, steps to the value of the enclosing form.
Next Steps to the start of the next form, or behaves like Step if there is no next form.
Step To End Steps to the value of the current function.
Continue Runs the code until a breakpoint is reached.
Macroexpand Macroexpands the form under the cursor.
