auctex: Floats

 
 2.4.2 Floats
 ------------
 
 Figures and tables (i.e., floats) may also be inserted using AUCTeX.
 After choosing either 'figure' or 'table' in the environment list
 described above, you will be prompted for a number of additional things.
 
 FLOAT POSITION
      This is the optional argument of float environments that controls
      how they are placed in the final document.  In LaTeX this is a
      sequence of the letters 'htbp' as described in the LaTeX manual.
      The value will default to the value of 'LaTeX-float'.
 
 CAPTION
      This is the caption of the float.  The default is to insert the
      caption at the bottom of the float.  You can specify floats where
      the caption should be placed at the top with
      'LaTeX-top-caption-list'.
 
 SHORT CAPTION
      If the specified caption is greater than a specific length, then a
      short caption is prompted for and it is inserted as an optional
      argument to the '\caption' macro.  The length that a caption needs
      to be before prompting for a short version is controlled by
      'LaTeX-short-caption-prompt-length'.
 
 LABEL
      The label of this float.  The label will have a default prefix,
      which is controlled by the variables 'LaTeX-figure-label' and
      'LaTeX-table-label'.
 
    Moreover, you will be asked if you want the contents of the float
 environment to be horizontally centered.  Upon a positive answer a
 '\centering' macro will be inserted at the beginning of the float
 environment.
