Behold the WP-30S

[Sanjeev Visvanatha]

So, 30S uses many of the same primary keys as 30B in the numeric area. An obvious proposition for minimal transformation would be to print Shifted function labels in this area only, using similar blue colour as 30B. Full key labels on the upper half of the keyboard and other spots where both Primary and Shifted functions differ from 30B.

Compare layouts of the 30B and 30S:



As for Alpha labels, a transparent row with printed Letters could be placed beneath each row requiring them. Of course, you need to obscure "Black S".
