Q:

Where is "close diff window" in Intellij keymap and/or menu

There is a bug in latest intellij that "escape" no longer closes popup "diff" windows such as 

compare to clipboard
compare with Git
show History

I would like to do a workaround by closing the window via something like Option-F4 or Control-W.  But where is the Keymap entry for closing these windows? I have searched on close and there is no entry.
The last fallback is to go the snail way - to mouse over to click on the red "close window" button: but any mouse movements are slower than a keyboard shortcut. 
Updated information Note: the normal "close window" keys (i am on Mac) do not work.
Here is the IJ bug entry  https://youtrack.jetbrains.com/issue/IDEA-142932
Another update  Here is key bindings: notice there is NO Close Editor Tab instead only Close All

A:

I'm using OS X Yosemite and pressing Cmd + F4 has the desired effect of closing the window. Cmd + F4 is bound to Window / Editor Tabs / Close.
