Some time ago someone on this forum helped me with the attached coding.
The page is in:
www.pinyinology.com/keys/keys2.html
When clicking the ok, the letters will change one by one. I like the
four letters change at same time, rather than one by one. Also, can I
add another set of symbols, such as ♣, ♦, ♥ and
♠, to the rotation? And then add more sets?
Thanks a lot. Following is the code:
