[news.eclipse.platform] Re: TextEditor problem.

Hi,
First, thanks for your help.

And there is another problem:
In my own text editor, I want the comment and uncomment (just like in
the java editor, you press the Ctrl + /, the rows selected are commented
or uncommented). So I followed what the jdt does: a command and a
binding, but what my editor does is different, it always comment the
selected rows even if they are commentd already. And in the jdt, I find
a command "uncomment", but no binding to this command.
and what should i do to make my editor works just like the java editor?

Hope that you can understand me.
