To get multiple names, add 's'.  On Windows, one uses control-leftclick 
to get multiple names.  Don't know about other systems.

 >>> fd.askopenfilenames()  # ^click 4 names
('F:/Python/dev/27/Lib/idlelib/aboutDialog.py', 
'F:/Python/dev/27/Lib/idlelib/AutoComplete.py', 
'F:/Python/dev/27/Lib/idlelib/AutoCompleteWindow.pyc', 
'F:/Python/dev/27/Lib/idlelib/Bindings.py')

The limitation is that this will not work if any of the file names 
contain astral (non-BMP) chars because tk cannot handle such characters.
