Tar mode defined in `tar-mode.el':...
   0 .. 9		digit-argument  (binding currently shadowed)

Shadowed by what?

   e .. f		tar-extract  (binding currently shadowed)

   C-d		tar-flag-deleted
   RET		tar-extract
     (that binding is currently shadowed by another mode)
   C-n		tar-next-line
   C-p		tar-previous-line
   SPC		tar-next-line
     (that binding is currently shadowed by another mode)

Say what mode on each of such lines!
