Bolding – Normally used to emphasize headings. Avoid using to
emphasize key points—if you photocopy the text, you may lose
the bolded effect. Instead, make it into a note (see Text Boxes).
Italics – Normally used to identify emphasized or new
words. We’ve used italics here to introduce new terms
that are also defined in the glossary. Italics can also be
used for document titles, such as the title of a form or a
manual.
Underlining – Commonly used when
working with typewriters, but virtually
never seen in manuals. Avoid
underlining.
UPPER CASE – Often used with typewriters for headings because of the lack
of other available heading attributes. All upper case letters, however, slow
reading speed because of the loss of characteristic word shapes—words in
mixed case have a shape that aids in their recognition. Avoid using all upper
case headings, except for acronyms and abbreviations.
SMALL CAPS – If acronyms and
abbreviations are set in full capital
letters like this—SPCA—they are too
dominant and will jump out visually. It’s
better to put them in small caps like
this—SPCA (usually 2 points smaller
than the text) to give them about the
same visual dominance as other words
in the text.
Courier Bold – Sometimes used in computer end-user manuals to identify words that can be read from
the computer monitor.
<Carets> – One of several possible ways of
identifying keys on the keyboard. For example,
“Press the <Enter> key.”
Screening – A light dot screen, such as this one, can
be applied to highlight important text, particularly
for caution or warning notes.
