I am using IDEA 12
I press enter (as I used to, long ago, with prior versions of IDEA) and what now happens is that the refactoring does not complete -- a linebreak is inserted within the new identifier I am choosing. How could that ever be correct?
I have altered some of the keymappings to make IDEA more Mac-like (I did not find the Mac-like template provided very well done -- e.g., cmd+G and shift+cmd+G have to be "find next" and "find previous" or my ears emit steam), but the modality of the thing I am doing and the total restriction against having whitespace within an identifier should never permit this to be broken, as I'd deem it now.
Is there a way I can export my Mac-like keymap for you to see? is there a way to diff two keymaps to see what might be off?
