SOLVED CKeditor: Skins, & Tab spaces Indenting:

[Arugula]

2 Question/Problems:

— In CKeditor's config.js there is this line that sets the tab spaces:
config.tabSpaces     = 10;    
that seemed too much, so I changed it to read:
config.tabSpaces                   = 5;    
BUT it continues to output 10 speaces whenever I hit the tab key!

—2:   I also tried to change the editor skin, by unzipping a new CK theme into this folder:
\admin\template\js\ckeditor\skins\
And editing this:  
config.skin   = 'getsimple';
to:
config.skin  = 'moono-dark';    
BUT it failed to make any appearance change at all.
