I've played around with it a few times through the years, with 
small mass loads and stiffeners of various kinds, looking for 
a quick cheap dodge. A top plate or longer key button helps, 
but it's sort of expensive for an "oh, by the way" noise 
reduction fix that doesn't bother the owner at all. An easy 
magic fix would be a good thing to have next time it comes up.
