Thanks for all the great tips and the reference link. I wound up using:
nnoremap <expr> <s-cr> foldclosed(line('.')) == -1 ? "\<cr>" : "zA"
nnoremap <expr> <cr> foldlevel(line('.')) ? "za" : "\<cr>"
BTW, is there a way to set the foldlevel using a mapping? I use the
SimpylFold plugin, which is great, but automatically sets the foldlevel to
expr, which prohibits me from manually folding.
Thanks!
