Now that I know where to look, I went back and tried to find out why my
search for a variable/object with the name "parameters" didn't show it.
It turned out that I must open an object at least once for the search
function to be able to find its children.
This didn't make much sense to me. If I am using a search function to
find something, it usually means that I don't know where it is. My be I
am using the wrong search method but the one in the variables view
doesn't seem very helpful.
Am I missing something?
Is there a better way to search the variables in the variables view
during debugging?

Do you mean "Find..." in the Variables view context menu? This one
isn't really a search. It allows you to specify a filter to limit the
list of currently displayed variables to make it easier to select one
when there is a whole bunch of variables. I'm not aware of a search
that searches into objects that are displayed in the variables view.
Cheers,
Larry

Yes, it looks like I misunderstood the use of Find. It also looks like
Find is really something between search and limit display because if I
collapse a node in the view the Find list still lists the objects that
are hidden. It lists all the variables that have been looked at, not
just the visible ones and it doesn't really limit the display, it just
takes you to that variable.
It would be nice to have a search feature.
Thanks,
