helm-case-fold-search is smart

Documentation: Adds ’smart’ option to ‘case-fold-search’. Smart option ignores case for searches as long as there are no upper case characters in the pattern.

How to search lowercase? I guess I could do that by changing the helm-case-fold-search but then I'd have to keep changing the variable with elisp.. Is there an interactive way of doing it?

  • There is some discussion here. I suppose you could write a function that toggles the value of helm-case-fold-search, for example, by setting it to nil with a prefix arg.
