Keyboard shortcut for right-click in current cursor position on OS X? ('Menu Key' on Windows)
In researching this particular issue, I ran a accross a particular app called Shortcat.

You can create a keyboard shortcut to select an element and click or right-click where your pointer is.

Note:  the right clicking function that brings up the menu where the pointer is seems to be OS X convention.

I tried this in Word and One Note for Windows as well as OS X.  In Windows, when you press the "right click key" or simply right click, it will bring up the contextual menu where your cursor is.  In OS X, it will bring up the contextual menu where your pointer is.
