This is a bit of a followup on https://emacs.stackexchange.com/a/27680/46612 and cycle through completions while showing completions buffer
I have set the completions format to vertical:
- start
emacs -Q M-xset-variablecompletions-formatvertical
Now when I use find-file:
C-x C-f<TAB><TAB>
I get a directory list sorted vertically.
Click on a completion to select it. In this buffer, type RET to select the completion near point. 6 possible completions: ../ AB ./ B A CC but when I use M-<down> to select one of them, the selection still moves horizontally. ie the order of suggestions is
../- `AB
AB ./BACC
This seems rather odd and counter-intuitive to me. (with the completions-format left at its default value, the selection still moves horizontally (kind of … the down key always goes right, regardless of setting), but that means suggestions get selected ../, ./, A, AB, B, CC, which I prefer.)
Is there a way to make minibuffer-next-completion (my understanding of what M-<down> calls) respect the original sorting of selections and move vertically with the vertical format?
