use of ME in behaviors

I'm trying to understand behaviors so as to be more adept at using them.
I've examined the scripts of the datagrid library, which give much cause
the private command_initialize
we see references like:
set the borderwidth of scrollbar "dgHScrollbar" of group
"dgHorizontalComponents" of me
but all these scripts are in a button "data grid"
So I am trying to understand what "me" references.
In order for there to be a scrollbar of a group of "me" , "me" would
have to refer to a card
or "bigger" parent group, or stack.
Did I get that right?
I am trying to understand how to reference controls "adjacent" to the
child object of a parent behavior.
e.g. main stack/card 1/field "SymbolName"
main stack/card 1/btn "Dog" # with behavior set to the long id
of button below:
substack ("behaviorVault")/button "showName # used as a behavior for btn
(and other buttons on the same card)
Now, in the behavior button I want to refer to objects on the card with
the child buttons
that use that behavior... so I'm trying to determine best practices.
When I click on a button on the main card, I want the name of the button
to pass to a field and the field to be shown, kind of like a tool tip of
this button is in a substack, but the child buttons and other field is
on card 1 of the main stack
A simple reference fails...
put the loc of the target into tPosition
put the shortname of the target into tName
put tName # it works... I get "Dog"
put tName into fld "symbolName" # fails
set the loc of fld "SymbolName" to tPosition # fails; reference is
not explicit enough
show fld "symbolName" with visual effect dissolve # fails; reference
is not explicit enough
send "hideName" to me in 5 seconds
hide fld "symbolName" with visual effect dissolve # fails;
reference is not explicit enough
I guess I can set the defaultstack to the main stack but I just wanted
to check if there is another way to establish the "card context" of the
child objects, in the behavior script of those child objects. It
seemed from the data grid stack that "of me" would could work, but a fld
on the same card is not a property of an adjacent button (whose behavior
is on another stack/card)
