How to add action to global searchable actions list?

Hello,
In my plugin I create action, but it doesn't appeared in global actions list(Ctrl+Shift+A).
In com.intellij.ide.util.gotoByName.GotoActionModel#collectActions I see that collected only actions from main menu.
Is there way to add my action to this list without adding action to main menu?

Thanks
