Jumping btw in-text citation and endnote

I’m using EndNote X6 and Word 2010, and would like to jump between the in-text citation and the endnote. I can ctrl-click to jump to the endnote, but can’t find a way to jump back up to the in-text citation. (I can do this in Word by double-clicking either the citation number or the endote number.) Is there a way to do this using EndNote X6?

In Word, the “return” key strokes a hard to find!  

try Shift +F5 or Alt+Back arrow.  (PS – it only works right after jumping down)
