The labels underlined in
red call alpha catalogs.
Labels underlined in green
and labels shown between
heavier white key contours
do not append characters
directly – all other
alpha
to
labels do.
If you print this virtual
keyboard in the size as
given below, you can
attach it to the back of
your WP 34S for ready
reference. This will serve
you well also for learning
the Greek letters and their
relation to their Latin
homophonic siblings.
Thereafter, you may slide
it 'under the hood' where
the batteries live, as sort of
a Quick Reference Sheet.
