How to open or close all documents in a book at once?

[dublove]

I found the shortcut for storing all documents in a book (set under View Navigation):
Ctrl+Shift+Alt+S

（This may not be very scientific, as it is possible to save the documents that  outside the book）
But did not find a command to open or close all documents in the book at once.

pper right corner, right click doesn't have this function at all.

There is a way to open multiple documents via the book panel, but it's a bit iffy.

Select the first document in your book panel, then hold Shift and click on the last document, this way all documents should be selected. Now double click (without holding Shift) on any of the selected documents and all should open. At least this works on MacOS.

Closing all documents can be done by Command + Option + W on Mac, this is a system wide shortcut to close all windows of the active program. I don't know if there's a windows equivalent for that.

Closing a document after selecting all will also prompt to close all documents.
Thank you very much.

Assuming your book is active, this will close them. Can be reversed engineered to open them too.  

try {
 var b = app.activeBook;
} catch(e) { exit(); }
 var bcs = b.bookContents;
var i = bcs.length;
while(i--) {
   try { bcs[i].close(SaveOptions.YES); } catch(e) {}
}

This one didn't respond.
I don't know what went wrong.

Open all book documents: Select desired files listed in bookfile; double-click on any of the selected files.

Save all open documents: Cntl-Alt-Shift-S/Cmd-Opt-Shift-S.

Close all open documents:  Cntl-Alt-Shift-W/Cmd-Opt-Shift-W. (I recommend saving all first or your will have to respond to each unsaved document.)
