Easily changing and editting default lexers in Code::Blocks

It's quite an easy task to accomplish. All you need to do is file replacement. Go to the Code::Blocks directory > share > CodeBlocks > lexers.
Then choose any lexer ".xml" and make a copy of it.
Now rename the older one with something like "oldname"+x.xml and the rename the new copies so that they become replacements.
Now edit the file as you want to meet your needs.

I did this for adding a "Default" color to the HTML/PHP lexer. It helped me build a theme. The default Lexer didn't have any Default color defined. So I increased the amount of Styles it had and just added "Default" from the Cpp Lexer. Neat thing just let me have a new Syntax Highlighter for PHP & HTML.
