For single-value properties, since I mainly use in-line syntax, I can search for "key:: value" (with quotes) which achieves the same thing. That approach should work for yaml as well unless you're unlucky. With double colon syntax "key:: " is safely like [key] since I never use double colons in my writing. It's less safe if using yaml. Searches on multi value keys is harder to do, but OR can get you there if there aren't too many.
