title: How to make the spyder Ipython Console display function arguments tooltips automatically?
body: <p>I am using the Spyder which comes inside the Anaconda3 IDE. I found the Ipython Console here is very helpful in the sense that when I type in a function, the arguments and default values will come up automatically. When I used to use Jupyter notebook, there is no such functionality.</p>
  <p>What I mean is like this:</p>

  <p>When you just typed the function name and a left bracket, the <code>Arguments</code> help window just pop up.</p>
  <p>However, my problem is that, sometimes, in the middle of this function completion, in this example, I finished typing bottom=a, but I forgot what should be passed to width, so let's say I pressed <code>Alt+Tab</code> in windows system to check it out in a PDF. Then I press <code>Alt+Tab</code> to switch back to Ipython console, but now the <code>Arguments</code> help window just dispeared.</p>
  <p>My question is is there any shortcuts to make the it appear again? Typically, I just have to clear all my arguments, and go back to type the left bracket another time to make it appear to help me specify the arguments, but this is unkind.</p>
