Those are not steps, those are RESTARTS.

What you have to do to invoke a restart depends on the implementation
and on the debugger you are using.

With slime, when you are in a sldb buffer you can just type the digit of
the restart, or you can move the cursor on the line of the restart and
type RET.

With slime, when you have interactive restarts, the interaction will
occur in the slime-repl buffer.
