Thank you for your response. I tried it and it worked fine.
I have another question about the code snippet. I have weird highlightings between the current line and the code snippet.
When a snippet is inserted on my editor, the current line highlighting is canceled. And when I start editing one of the snippet fields, the current line highlighting appears and the code snippet highlightings are canceld instead. Then, when I press [Tab] key to move to other snippet field, the current line highlighting is canceled again and the code snippet highlightins appear.
This does not occur on your Sample Browser. So I think I'm doing something wrong but cannot find out what it is. Could you give me some advice on this, please?
Thank you.
