  often speak of the character ``at'' a position, meaning the character
  after that position.
  
!   Positions are usually represented as integers starting from 1, but can
! also be represented as @dfn{markers}---special objects that relocate
! automatically when text is inserted or deleted so they stay with the
! surrounding characters.  Functions that expect an argument to be a
! position (an integer), but accept a marker as a substitute, normally
! ignore the marker buffer.  Of course, markers used this way usually
! point to a position in the buffer that the function operates on, but
! that is entirely the programmer's responsibility.  @xref{Markers}.
  
    See also the ``field'' feature (@pxref{Fields}), which provides
  functions that are used by many cursor-motion commands.
