      Press <Z> to show all config symbols which have prompts.

    I myself found this useful too. For example, I need to test
    ftrace/tracing and want to be sure all the tracing features are
    enabled, so I  enter the "Tracers" menu, and press <Z> to
    see if there is any config hidden.
    I also noticed gconfig and xconfig have a button "Show all options",
    but that's a bit too much, and I think normally what we are not
    interested in those configs which have no prompt thus can't be
    changed by users.
          --- Tracers
          -*-   Kernel Function Tracer
          - -     Kernel Function Graph Tracer
          [*]   Interrupts-off Latency Tracer
          - -   Preemption-off Latency Tracer
          [*]   Sysprof Tracer
    Here you can see 2 tracers are not selectable, and then can find
    out how to make them selectable.
