Let the space keystroke invoking the drop-down completion window if possible.

edit

Hi,

When I input the following code:

  from os import<spc>

After I clicked the space key, I want to see the drop-down completion window but it doesn't appear. And in order to see the completion window, I must give a letter, say ``p''.

How to let wingide immediately invoking the drop-down completion window instead of waiting for me input some letter?

Regards
