I finally have some styles I think I can use as a Default.
When I enter a New Line, select the Style and start typing everything is OK.


HOWEVER, if I SELECT a line of text with an existing style, and then SELECT the New Style, if does NOT change.
Even if I get a popup message box asking to REAPPLY the style, NO change occurs.
Working with the line that will NOT change, sometime I can get it to change, other times NOT, by DELETING the Carriage Return and the ADDING in a NEW Line, or other actions related to that line.


For example:
Style1 (original)

The original first line is indented and all subsequent lines are indented so the entire paragraph is identified as Style1.


Style1-FirstIndent (NOW)

ONLY the first line is indented with the rest of the paragraph (following) at the left margin (Body TEXT).
