For example the text:

select * from money m
where id in
(
142342
234234
453453
245422
);

I want to put in the end of the line with a comma...
Ctrl+H
Select in the field "Find" (the end of a word and the end of the line)
>$
In the box: "Replace" to Replace what has been, and plus comma)
\0,

If you find no end of a word, it generally does not find the end of the line, and so finds, but the replacement replaces the last letter on \0,
The same thing happens when you find the last character in the string
.$
