Ctrl+Q

When you use Ctrl+Q (View | Quick Documentation), the Documentation popup is shown.

Then, if you click in the upper-right corner of the popup, the popup transforms into a tool window. As a result, the tool window becomes available in the View | Tool Windows menu.

To turn the tool window back into a popup, click again.
