How To Change Font On Side Boxes

I am new to this so excuse me if this has been asked before, I have had a look through the threads but have not found an answer so here goes.

I want to change the the words / fonts of the headings in the side boxes such as Categories, Languages, Information etc etc, can anyone point me in the right direction on how this is done.

Thankyou in advance

The fonts can be changed in the stylesheet by specifying the sidebox or sidebar id's and the desired font.

The text is defined in language files. You can find the correct files to edit by going to admin > Tools > Developers Toolkit and entering one of the titles in the lower left box. Select all files and search. Then open the file in a good text editor and edit as desired.
