Richard,
Thanks for the information. I appreciate it much.

Most visual attributes (textFont, textStyle, textSize, backgroundColor,
foregroundColor, and others) are inherited using roughly the same chain
as the message path: control, background (if present), card, stack, home.
If you set the desired properties to empty in the controls themselves,
you can set them at the stack level and those controls will take on
those appearances.
Tip: to find the property settings for a control you can of course just
get it from the control, e.g.:
get the textFont of fld 1
But if you've set the property to empty and want to know what value is
being inherited by it, you can use the "effective" keyword:
get the effective textFont of fld 1
That will return the value of the property nearest the control which has
a non-empty value, or the engine's default if nothing in the message
path has been set.
For example, if your field's textFont is set to empty and your card has
a textFont of "Lucida Grande", then using "the effective textFont" will
return "Lucida Grande". If the card's textFont is empty but the stack's
textFont is "Ariel", it will return "Ariel". If you later set the
textFont of the control to "Trebuchet", it will return "Trebuchet"
regardless of the value of any subsequent objects in the chain.
