CKEditor: how to define custom configuration file?

[mvlcek]

I see you set

Code:

stylesCombo_stylesSet: 'my_styles:/theme/Choice/styles.js',

which means that the file is located in theme/yourTheme/ ?

Yes, it contains references to the styles and thus I think it belongs into the theme's directory.

why do you define the toolbar in GSEDITOROPTIONS and not in GSEDITORTOOL?

With GSEDITORTOOL you can only set the toolbar to specific configurations (e.g. "advanced"), but not define it with exactly the tools you want.
