Hi

I don't know if that's what you're looking for, but I think you are talking about subscripts ("pedix" have assonance with italian "pedice", in english "subscript" )
if so, just type the dot "." after the variable name...
f.e. type
my.var to write [MATH lang=eng]my.var[/MATH]
P.S. in the wiki there are several
tutorials on using SMath
