Put your cursor on the paragraph that you want to modify
from the existing style, click on the word "Format" on
your tool bar. Scroll down and click on "Style." Then
the "Style" box will appear. At this point you want to
click on the "New" button at the bottom of the box because
you want to create a new style.
When the "new style" box pops up, you name the new style
in the upper left hand box, click in the "Add to template"
box because you want this new style added to your current
style template, then click on "automatically update"
because you want all paragraphs that you attach to this
style automatically updated if, in the future, you refine
and change this particular style.
Now go click on the "format" box at the bottom of the "new
style" box and within this box, you can format everything
from the font, to paragraph spacing, alignment, etc. All
formatting is saved within this new style name. Once
you've completed your new style, you click
on "OK" ....then "Apply". You now have your new style.
Whenever you need to use this style, you simply go to the
style menu located in the upper left corner of your MSWord
screen, scroll through the available styles, and click on
the one you want to attach to that particular paragraph.
If you hi-lite several paragraphs at once, you can attach
that style to more then one paragraph at a time.
Hope this helps!
