How do I display the function parameters help box when I'm in the middle of typing them? By looking at questions like this one, it seems that I have to hit either Ctrl+SPACE or Ctrl+Shift+SPACE, but neither of these seems to work. The parameters are displayed when I type the (, but then they disappear.
BTW, a related question: It seems that when I'm typing the name of a class the parameters box isn't displayed. I have to type .__init__
after the class name to see the help box. Is this like this or am I missing something?
