IntelliJ IDEA 13 has the new Search Anywhere feature. It sounds like it might be useful, but so far it just gets in the way. It\'s mapped to some kind of magical shift-
It's called Search Everywhere, and it's present in keymap.
For me it's perfectly disabled.
EDIT As I'v found it is hardcoded now, and will popup at doubleshift source
There is also an issue at jira, about this problem.
I hope it will be fixed soon.
