 blue, and alpha (transparency/opacity). You can use a [color picker](https://www.google.com/search?q=color+picker) to help you out. 
 The extensions section is fairly self-explanatory.
 
+You can set settings for specific programming languages like this:
+
+```
+[HTML.core]
+# set tab width for HTML files to 2
+tab-width = 2
+```

 To reset your ted configuration to the default settings, delete your ted.cfg file (`~/.local/share/ted/ted.cfg` on Linux,
 `C:\Users\<your user name>\AppData\Local\ted\ted.cfg` on Windows) or move it somewhere else.
