Steve: Thank you very much, a very good answer.
Can you tell me where can I find a tutorial in order to use?
I tried to use but I could not get a good result, so I suppose I am not using well.
If I want to take off a line I have to put the line answering by \n
For ex. the line is
<center>
I will have to put in: "find what": <center>\n
but it does not work.
Thank you very much Steve.
