questions about using the editor of pythonWin--from a new comer

[littleneo]

Hi,
Is there anybody know how to show the line number in the source code using
the editor of pythonWin? Another problem is how to find the folder of a file
in the editor, since it only shows the file name. If I need to open several
files at the same time, if there is a convenient way to choose the needed
file without organizing the files manually. The windows will cover each
other.

Thanks a lot!
