Control charcters cannot be seen?

[willy]

Hi,
does in Calc exist a way to show CTRL-RETURN paragraphs, protected blank spaces or other control characters in a cell (as I can do it in sxw-file)?
Today I work with two windows, in one I see the copied column in Write, showing the text with control characters, in the other is the calc-file. In a bigger text-database with defined width an heigth of the cells this is quite uncomfortable method to edit.
Also the search-command doesn't help enough. It only shows the cell with the includes paragraphs but not the position an no protected blank spaces. What can i do?
