Terry,

You could do something like the following. First we write a general
definition.

MatrixStyle[opts___][mat_] := StyleForm[MatrixForm[mat], opts]

We could use it directly, but more often you will want a shorter special
definition.

MatrixForm8 = MatrixStyle[FontSize -> 8, FontFamily -> "Helvetica"];

testmat = IdentityMatrix[5];

Using the general definition...

testmat // MatrixStyle[FontSize -> 8, FontFamily -> "Helvetica"]

Using the short definition.

testmat // MatrixForm8

Hi All:
   Is it possible to construct a special form of MatrixForm (say
MatrixForm8) that does the same thing as the
default version of MatrixForm except that an 8 point font size is used,
and maybe a different
font type is used?  How would one go about this?   Of course I would
want the default version of MatrixForm
to perform as it always does.  That way I can pick and choose which I
want to invoke on any matrix expression.
I need this to help in displaying long symbolic elements of a 3x3
matrix.  Thanks in advance to all who reply?
