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-references 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.
'nocolour'
'nocolor'
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.
'bgnocolour'
'bgnocolor'
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,nocolour
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 'nocolour' rendition style will cancel the yellow
colour, leaving the text in the match the terminal's default colour.
(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.)
