A recursive grep in a directory should be the simplest thing, but I haven't found the recipe to get it to work yet. I'm juggling between the following commands and am not sure which has the functionality buried within it:
helm-find-files: The problem is this is really bad at finding a directory recursively.
projectile-find-dir: This is great at finding the dir! However despite using helm complete you don't wind up in helm mode, so the
C-u C-scommand doesn't work here.
helm-find: gets the recursion right but targets files, not directories
helm-projectile-find-dir: Seems to be what I want.
