A new EAP build 122.100 of IntelliJ IDEA 12 has been released. Updated Find Usages action now starts searching usages without showing a modal options dialog. You can use old Find Usages as well enabling modal options with additional Control (or Command) modifier in a shortcut, e.g. Control + Alt + Shift + F7 on Windows.
You can find the complete list of changes in the build.
