The file list on the right is divided in four sections:
Each section of files may have three sub-sections :
The bullet in front of each file can have three different colors:
The files belonging to the current theme are also in bold.
To modify a file, click on its name. Its content will be displayed in the editor. If the file can be overwritten you will be able to save it by pressing the Save (s) button.
Be careful: Modifications are applied immediately after saving.
If you modify a file that comes from the template set or the parent theme, the file will be copied into your current theme.
You can activate the syntax highlighting in your preferences (in My options tab).
To edit your template files, please check the list of template tags.
