info-stnd: Colors and Styles

 
 13 Colors and Styles
 ********************
 
 You can choose to highlight parts of Info's display, such as
 cross-references and search matches, using a variety of styles,
 including colors, boldface and underline.  Here are the variables that
 are available to do this:
 
 'link-style'
      Used for cross-references and menu entries.
 
 'active-link-style'
      Used for a cross-reference or menu entry when typing <RET> would
      have the effect of following said cross-reference or menu entry.
 
 'match-style'
      Used for matches from a search command.  (⇒Searching
      Commands.)
 
    Each of these is given in the '.infokey' file just as the variables
 in the previous chapter.  Their values are a comma-separated list of
 values in the following table:
 
 'black'
 'red'
 'green'
 'yellow'
 'blue'
 'magenta'
 'cyan'
 'white'
      Use the color specified for text.
 
 'nocolor'
 'nocolour'
      Turn off any color that was in effect, using the terminal's default
      color.
 
 'bgblack'
 'bgred'
 'bggreen'
 'bgyellow'
 'bgblue'
 'bgmagenta'
 'bgcyan'
 'bgwhite'
      Use the color specified for the background.
 
 'bgnocolor'
 'bgnocolour'
      Use the terminal's default background color.
 
 'underline'
 'nounderline'
      Turn text underline on or off.
 
 'standout'
 'nostandout'
      Turn 'standout mode' on or off.  Standout mode entails the use of
      appearance modes that make text stand out, and varies between
      terminals.
 
 'bold'
 'regular'
 'nobold'
      Turn boldface on or off.
 
 'blink'
 'noblink'
      Make the text blink, or not.
 
    Here is an sample excerpt from an '.infokey' file:
 
      #var
      link-style=yellow
      active-link-style=yellow,bold
      match-style=underline,bold,nocolor
 
 With this, cross-references are all yellow, and active cross-references
 are additionally displayed in bold.  Any search matches will be shown in
 bold, and underlined.  Moreover, if there is a search match inside a
 cross-reference, the 'nocolor' rendition style will cancel the yellow
 color, leaving the text in the match the terminal's default color.
 (Note, however, that the rendition styles for active cross-references
 take priority over those for search matches, so search matches there
 will still be displayed in yellow.)
