Keyboard shortcut to close documentation?

Question

Is there a keyboard shortcut that closes a documentation window opened with Ctrl+q? The ESC key doesn't seem to work and googling was not successful for me either. I'm on OSX with the cross platform keyboard map if that's any help.

The Problem

As I stated in a comment,

I just started using IntelliJ, and ESC worked for about 1 week. Then I changed something, and ended up requiring Shift-ESC. Annoying! I can't figure out what I changed.

I finally figured out why ESC stopped working. After an initial install of IntelliJ, the dialog is considered a "popup". If you open this popup with Ctrl+Q, and then click the pin icon at the upper right, it turns the popup into a normal dialog. This dialog behaves like the other views, which are dismissed with Shift+ESC.

The Fix

To restore the popup behavior, click the gear icon (upper right) and make sure "Show Toolbar" is checked. Click the big red X icon. This returns it to popup mode.

My life just got way better.
