1. 创建或编辑usertype.dat文件（此文件在VS安装目录下的Common7\IDE下面，比如我的就在D:\Program Files\Microsoft Visual Studio 8\Common7\IDE\usertype.dat），添加如下的关键字列表，每个单词占一行，如果你想添加你自己的关键字，也可以按照这种方式添加在usertype.dat文件中
2. 在vs中打开Tools->Options...->TextEditor->File Extension
填写你想使用的着色器文件扩展名，如fx, hlsl, vs, ps等等，然后Editor选择Microsoft Visual C++
3. 重新启动VS2005
关键字列表：
