Hi is it possible that a calendar can appear when you want to select a date in a field, at present im using the f5 button to automatically put a date in,
however im looking at the possibility of putting in an advanced date a number of years ahead, so is it possible to generate a pop up calendar,
is there a function key or simillar for this already?

Right, somehow it was inadvertently dropped in latest versions. (That is, the day-time picker was available in some really old versions.) I think this will be added back in the nearest maintenance update, which can happen at anytime from a few days to a few weeks depending on whether there will be any reported bugs to fix.
