Very nice...so,  from the Method Finder help:

"Or, use an example to find a method in the system.  Type receiver, args,
and answer in the top pane with periods between the items.  3. 4. 7"

do you put a number for EACH parameter...meaning if we were looking for a 3
parameter method we would put a 1. 2. 3. between the receiver and the
expected answer?

Thanks...I've seen the blurb in the Method Finder, but never quite figured
it out!
