Keyboard Shortcut for Find Citations

I have recently upgraded to Endnote X4 and Word 2011 (mac). I used to have a keyboard shortcut (in word 2004) to open the find citation(s) dialogue box, but I cannot do this in word 2011. The command does not appear on the customise keyboard shortcuts list, and I cannot record a macro that ends with the find citation dialogue box still open. I find the constant mouse trip to the top of the screen to click the endnote icons really frustrating, does anyone know how to make a shortcut?

With thanks

Mac OS 10.6.6 + EndNote X4.0.2 + Word 2011

Keyboard shortcut = Control + 7 [Find citation(s)]
