This is quicker:

  ListView1.Add(Key, Text).MoveFirst()

but there doesn't seem to be a way to request that an item be added *before*
some other item, or at the beginning. It's an asymmetric interface.
(Although in the backend of ListView's implementation, there *is* a flag
which lets you put elements before, not after, the given reference item).

PS: Generating keys via CStr(ListView1.Count) only works as long as you
never delete anything from the ListView. I often use a ListView for display
purposes only and don't care about keys either. Letting the ListView
generate a unique key in case the Key argument to ListView.Add() is Null
is a nice task for someone's first contribution to Gambas... ;-)
