When making this binding, I loosely justified it for myself with this
section from the Emacs Lips Manual, "Major Mode Conventions"

      It is legitimate for a major mode to rebind a standard key
      sequence if it provides a command that does "the same job" in a
      way better suited to the text this mode is used for.  For example,
      a major mode for editing a programming language might redefine
      `C-M-a' to "move to the beginning of a function" in a way that
      works better for that language.

      It is also legitimate for a major mode to rebind a standard key
      sequence whose standard meaning is rarely useful in that mode.   
For
      instance, minibuffer modes rebind `M-r', whose standard meaning is
      rarely of any use in the minibuffer.  Major modes such as Dired or
      Rmail that do not allow self-insertion of text can reasonably
      redefine letters and other printing characters as special  
commands.


Using this philosophy, Org rebinds C-a, C-e, and C-k to slightly modify
the behavior of these functions in headlines with tags.

C-x n s  seemed a logical key for this.
