I use multiple-cursors, and have recently set up on a new machine. Whenever you try to issue a command while multiple cursors are active, and multiple-cursors doesn't know whether it should run for each cursor or just once, it asks you.
However, one time I answered incorrectly! And now whenever I run
dabbrev-expand) it only does this for one cursor.
There must be some config somewhere that will allow me to reset this and either manually set it, or ask me again for this (or possibly each? Am hoping I can keep most of my previous answers!) but I can't find it.
I've tried searching for the files in
~/.emacs.d and seeing if I can find an obvious command to feed into
M-x, but to no avail - does anyone know what to do that isn't just uninstalling/reinstalling multiple-cursors and hoping for the best?
.mc-lists.elfile may be at the root of your home directory rather than in your Emacs config directory.
~/.emacs.d/.mc-lists.elis exactly what I needed to find!
