+.SH "MAGIC STRINGS"
+.TP
+\fB^#![ \\t]*/.*env[ \\t]+Rscript\fR
+.\"
+\*(mE recognizes the magic string on the first line of the file used to locate
+the  executable.  The  Rscript  files  may  be  extension-less  and  are  still
+recognized.
+.SH DESCRIPTION
+The  \fBR\fR  file type  template  provides  simple  hilighting of Python
+files, the template provides minimal hilighting.
+.PP
+File  recognition  is performed  using the standard file  extension  \fB.r\fR,
+\fB.R\fR or by the magic string.
+.PP
+It offers as well folding and support for displaying an outline of the
+functions of the R script for easy navigation using the 
+.Ht item-list 3
+command.  Further  is is  possible  to expand  abbreviations  either via short
+strings using the
+.Ht expand-abbrev-handle 3
+command and visual inserting abbreviations using the mouse by the
+.Ht abbrev-list 3
+macro. 
+.IP "\fBFolding and Information Hiding\fR"
+Generic  folding is enabled  within the R files. The folds occur about
+the \fBfunction\fR keywords located on the left-hand margin at the beginning 
+of the line if the smaller-minus assignment operator is used.
+The following commands are supported to show and hide the function bodies.
+.Ht collapse-all 3
+(un)folds all regions in the file,
+.Ht collapse-current 3
+(un)folds the current region.
+.IP "\fBList Items\fR"
+Item listing is available and the key  constructs of the file may be listed in
+the \fIitem-list\fR.
+.IP "\fBAbbreviations\fR"
+The  installation  comes with a default  abbreviation  file for R code  editing
+which  can  be  used  by  writing  short   abbreviations   like   "\fBmain\fR"
+for a default Rscript application outline,"\fBfor\fR",
+"\fBif\fR"  or  "\fBfun\fR"  -  for  a R  function  - and  then  pressing  the
+key-binding  for the 
+.Ht expand-abbrev-handle 3
+command.  The  list  of  abbreviations  can be used  interactively  in the GUI
+version of \*(mE using the 
+.Ht abbrev-list 3
+command.
+.IP "\fBShort Cuts\fR"
+The short cut keys used within the buffer are:-
+.IP
+\fB\*cc \*cc\fR \- Comment out the current line.
+.br
+\fB\*cc \*cd\fR \- Uncomment the current line.
+.br
+\fB\*cc \*ce\fR \- Comment to the end of the line with stars (*).
+.br
+\fB\*a\*ci\fR \- Restyle the current region.
+.br
+\fBf2\fR \- (un)fold the current region
+.br
+\fBf3\fR \- (un)fold all regions
+.br
+\fBf6\fR \- list items
+.br
+\fB\*e f6\fR \- close list items
+.SH BUGS
+Functions with using the equal operator for  assignments  are not shown in the
+function  outline,  this should be seen as a feature  which allow you to write
+hidden internal functions within other functions.
