These are called 'Tooltips'.
http://en.wikipedia.org/wiki/Tooltip
AFAIK, there is no way of creating a Tooltip for a UDF in Excel. In VB.NET
it is extremely easy to create a Tooltip, but not in Excel...well, certainly
not without a heck of a lot of work. Basically, no.
The closest solution I can offer is press Ctrl+Shift+A after you've typed
the first bracket...but that's not a Tooltip.
Good luck,
