Most defaults work this way: with no documents open, you change a setting and that becomes the default for new files, or if a document is open, changing a setting with nothing selected becomes the new default for that document. Changing defaults does not affect anything previously done.
For text, you can simply set the font specifications you want and they will become the new defaults, but it is better to acutally edit the [Basic Paragraph] style, IF YOU HAVEN'T already set text that you don't want to change. [Basic Paragraph] is the default style applied to anyting in your document unless you specify something else, and it appears in all new documents. Editing styles, though, will apply the changes in the defintion to all text to which that style is applied.
Well you’ve already gotten that answered but let me make my usual recommendations to beginners.
First, here’s a one week trial to Lynda.com where you’ll find a wealth of video training by the top experts in the world: http://bit.ly/fcGpiI
Secondly, buy a copy of Sandee Cohen’s Visual Quick Start Guide: http://amzn.to/rcr2jz
Best $18.00 you’ll ever spend.
That is very useful.
I'll be back!! Thanx to Bob, I think I'll be buying that book!
