Adding a shortcut for the create action

I just remembered this fact:

the N shortcut is already mapped to access annotations of a page.

So if we want to use N for new page, we’d need to break the consistency of the interface on new versions (and also find a new default for the annotation shortcut).

This shortcut was not properly documented on https://www.xwiki.org/xwiki/bin/view/Documentation/UserGuide/Features/KeyboardShortcuts , I’m updating it :slight_smile: .
