My problem: I have Ido-mode enabled and I want to edit (for example) a file .emacs in my home directory. I have no .emacs file there, but I do have a .emacs.d, and so ido assumes that I want to enter the directory when I do C-x C-f .emacs RET.
I've been trying to solve this for at least weeks, and I've got a couple work-arounds but I would really rather not have to do anything crazy.
You can either press C-j to accept what you have typed so far, or C-f which will drop you into regular find-file
