more font and styles

I was trying to install more font and styles on FCKEditor, but I can't do.
What I do for the fonts was to added a new font on the following statement

Code:

config.ToolbarFontNames = ';Arial;Comic Sans MS;Courier New;Tahoma;Times New Roman;Verdana' ;

in the file fck_config.js, but it doesn't works.

For the new style, I added a new class in the file
fck_editorarea.css, but I doesn't works neither.

Any idea about how to do it ??
I'd like to modify the spaces (height) between the lines of text too...


Thanks !
