Thank you for the reply.
In the folder I found cbKeyBinder10.ini which was correctly last modified today, it contains my shortcuts.
Unfortunately, default.conf was modified on May 15, that's when I installed codeblocks. I am afraid it does not contain my color settings.
I did search on all files that were modified on 2011-05-30 but I got 10K+ files, I do not think I can find the right one among them.
Is there any other config file that codeblocks uses to save color settings? I made the changes directly to default scheme.
Thanks again!
