So M3 allows fields to be arrays. I.E. You can force a field to accept a set of stacking values. E.G. A Common application of this is Credit Cards. Often times, they combine the VS, MC and DS cards into a single array. 


For those of us who enter these values in nightly, it can be a huge pain to stop the 10-Key input of numbers into M3 to move the mouse to the elipses (. . .) that opens the array. Do we know of a keyboard command to open these arrays? ESC can close them! 


If no, to the devs of M3, could we perhaps get one?
