'=' and highlight

'=' and highlight

[sergio]

Hello.

Why org mode highlights this lines with bright text color:

={motion}    indent code
==           indent line

?

From the first '=' till '=='.

Hints:
(info "(org) Emphasis and monospace")

Put the cursor on a character in the indicated range and do

C-u C-x = 

Look at the "face" property.

Face for fixed-width text like code snippets.
...
    Foreground: unspecified
...
       Inherit: shadow
...


How org-mode decides, when to use this face?

See the 2 following vars:

- org-emphasis-alist
  Variable: Special syntax for emphasized text.

- org-emphasis-regexp-components
  Variable: Components used to build the regular expression for
            emphasis.

See the docstring of `org-emphasis-regexp-components':

,----
| Components used to build the regular expression for emphasis.
| This is a list with five entries.  Terminology:  In an emphasis string
| like " *strong word* ", we call the initial space PREMATCH, the final
| space POSTMATCH, the stars MARKERS, "s" and "d" are BORDER characters
| and "trong wor" is the body.  The different components in this variable
| specify what is allowed/forbidden in each part:
| 
| pre          Chars allowed as prematch.  Beginning of line will be allowed too.
| post         Chars allowed as postmatch.  End of line will be allowed too.
| border       The chars *forbidden* as border characters.
| body-regexp  A regexp like "." to match a body character.  Don't use
|              non-shy groups here, and don't allow newline here.
| newline      The maximum number of newlines allowed in an emphasis exp.
| 
| Use customize to modify this, or restart Emacs after changing it.
`----

In your case, I think you want to prevent =...= to emphasize
(i.e. shadow) the text when the "border" character is `{'.

HTH,
