shows one entry for each section of the presentation (in this case 1,2 and 3). For my purposes -- rather than showing entries for each section -- I need to have entries for the subsections displayed, so that where it reads "1,2,3" now it will then read "a,b,c".
I have been plowing through the Beamer manual, but without success. Suggestions anyone? Thanks.
