+-----------------------------------

+  If you type 'Z', then kconfig-mconf will change what is displayed.
+  Normally, only enabled features that have all of their dependencies met
+  are displayed.  That is, of course, not very useful if you would like to
+  discover new options or if you are looking for an option and do not
+  realize that the dependencies have not yet been selected and, hence, it
+  is not displayed.
+
+  But if you enter 'Z', then every option will be shown, whether or not its
+  dependencies have been met.  You can the see everything that could be
+  selected with the right dependency selections.  These additional options
+  will be shown the '-' for the selection and for the value (since it
+  cannot be selected and has no value).  About all you do is to select
+  the <Help> option to see what the dependencies are.
