How to diable all the fonts other than Tahoma in fckeditor

Hi,

I need to have consistent font in my editings. I decided to disable all the fonts except "Tahoma".
( I have disabled all the fonts except Tahoma in editor toolbar. But copy from other editors having the font which
it was in the other editors).

Is there a way to carry out this?

Kindly help me.

Thanks in advance.

Regards
Suresh
