Any frame in the Backtrace list can be operated on using commands in the Frame menu. This menu is also available as a popup from the backtrace area itself. The commands available allow you to operate on the function displayed in the selected frame.
Choose Frame > Find Source to search for the source code definition of the object pointed to by the current frame. If it is found, the file is displayed in the Editor: the cursor is placed at the start of the definition or at the subform which cause the error, if known. The form is highlighted. See The Editor for an introduction to the Editor.
Frame > Documentation
to display the Common Lisp documentation for the object pointed to by the current frame, if any exists. Note that this is the result of the Common Lisp function
documentation, not the supplied manuals. It is printed in a special Output Browser window.
Choose Frame > Method Combination to display a Generic Function Browser tool in the Method Combinations view for the arguments in the selected frame. This command is only available when the selected frame is a call to a standard method. See Examining information about combined methods for information about using the Method Combinations view.
Choose Frame > Restart Frame to continue execution from the selected restart frame. The action that is taken when choosing this command is printed with each restart frame in the Backtrace area. Note that restart frames must be listed for this command to be available: see Configuring the call frames displayed for details.
Choose Frame > Restart Frame Stepping to step through execution from the selected restart frame. This frame becomes the active frame in a Stepper tool. See The Stepper for information about using the Stepper tool.
Choose Frame > Return from Frame to resume execution from the selected frame. A dialog prompts for a value to return from the selected frame. Previously entered values are available via a dropdown in this dialog. This option allows you to continue execution smoothly after you have corrected the error which caused entry into the debugger.
Frame > Break On Return from Frame
to trap execution when it returns from the selected frame. This command prints a message telling you that the trap has been set, and when Lisp returns from the frame it calls
break, allowing you to enter the debugger again.
Choose Frame > Trace to display the standard Trace menu. This lets you trace the function in the selected frame in a variety of ways: see Tracing symbols from tools for details.
