Highlighting for .lco files

[teufel7]

Hey,

is the highlighting a part of the plugin or IDEs?
If plugin, is it possible to add?

Best regards

I think it has to do with the scrlttr2 KOMA-script class, right? Can you explain what the file is for? It looks like it has to be valid LaTeX, is that true?
In case it's valid LaTeX, you can mark it as a LaTeX source file by adding it to Settings > Editor > File Types > LaTeX source file.

In this file are formatter for the letter-class and package imports.
Yes and it is valid Latex.

Settings > Editor > File Types > LaTeX worked.
