Suppose I have the path
/hello/world/file.txt
In other editors such as Atom, Sublime Text or Visual Studio Code, when navigating to the file using fuzzy search (CTRL+P), I can for example input hewofi and the editor shows me this file as search-result. In PhpStorm however, I have to use directory-separators, i.e. he\wo\fi otherwise it doesn't find the file.
How can I configure PhpStorm so that it's fuzzy search ignores path separators?
No way. Now possible.
AFAIK (although not 100% sure) originally Navigate | File worked on file names only -- ability to also include path names was added later .. and you have to use them to denote that those letters are belonging to the path rather than file.

UPDATE 2017-10-28: the aforementioned ticket is now implemented and will be available in 2017.3 (you can grab EAP build if you wish to test it before the official release).
