Ok, that looks pretty simple but I'm not quite sure yet how to combine 
my two definitions so I won't have to type '\markup' each time.  (see 
below).

Even so I would like to understand the scheme code.  I have been 
searching through the scm directory trying to make sense of all of 
this.  In scm/translation-functions.scm I found references to numerator 
and denominator which are listed as properties in the manual. 

1. Is that code actually referring to the same properties listed in the 
manual?

2. In that same file there is a reference to 'make-bold-markup' but I 
can't find it's definition anywhere.  I thought that might help me 
discover how to define 'one' so I can do R1*3/4^\one as you have suggested.

Can you comment on either of these two points so I can do more of this 
on my own?

I only yesterday discovered that you had used the new version of the 
code you wrote (for me?) some time ago as an example of setting 
properties.  That helped me generate a newer version of many property 
shortcuts I have that are based on the original help you gave me.

Thank you very much for that!
