thanks, that worked, I was down the auctex rabbit hole, and got stuck on a 'cannot load file... cdlatex' or some such... C-c C-x C-l worked out of box! Weird, once I have C-cxl'ed a fragment to rendered latex, and the C-cc'ed back to monospace, I am no longer able to insert superscript and subscript symbols, and it complains about cdlatex-superscript or cdlatex-sub-superscript...
