How to improve performance of Pycharm documentation fetch

Question

When I'm hovering over some Python method in Pycharm, the "quick documentation" window appears instantly, but it will still be fetching documentation for a few seconds before the document appears.

How do I get the documentation to appear instantly without the fetch delays?

I have experienced this issue before in Android Studio (which is a modified version of IntelliJ IDEA) and managed to solve it with the help of this thread: Android Studio quick documentation always "fetching documentation".

Instead of getting Android Studios to fetch the information online each time quick docs appears, the answers suggested downloading all the documentation for Android in a package called the Android SDK Documentation and referring IntelliJ IDEA to that package. In Android Studios, this not only works with the core Android methods but also any library that gets imported into your project.

Can I do something similar in Pycharm?

No, I did not ask for the shortcut. I need to know how I can speed up the process of fetching the documentation so that it appears instantly. — Simon

No i didn't - it is not the artificial 500ms delay im talking about, it is the network operation to download the docs. I don't want there to be network operations to download the docs, i want them to appear instantly offline. — Simon

If you want reduce the delay of the quick documentation, you can go to:

Settings->Editor->General

In this window, search and enable (if it is not) the option:

Show quick documentation on mouse move

Now the Delay option should be enabled, so you can set the value that you prefer.
Remember that is in milliseconds.

Let me know.
