with the default configuration when I walk through $a_multi_word_identifier with Ctrl + Arrow Keys PhpStorm stops before and after the whole identifier. I want it to stop before the identifier, after the $, after each word and after each underscore, just like any other editor (except notepad) does.
(This is because I often take $identifier_for_some_case and make $identifier_for_other_case from it.)
I found some option regarding CamelCase (probably coming from the Java world) but not exacly the configuration for word boundaries. So where is it? In UltraEdit one has to edit the wordfile. Is there such a thing in PhpStorm?
