Which is a bit of a pain. Without restarting Emacs (how does one even do that 🤣) I have to upcase-char or insert-quoted “C” to get a capital ‘c’.

I have no idea what combination of keys I’ve hit to effect this change, but it does not happen on start-up.

Viewing lossage is not much help because quite a lot of time may have passed and my need to type “C”. (I am not Carl Carlson Chairman of the Classic Car Confabulation Committee. )

Does anyone have any ideas how even to debug this? I am flummoxed.

Many thanks!!

There is nothing funky about my keybindings…

(keymap-global-set "C-="     #'text-scale-increase) 
(keymap-global-set "C--"     #'text-scale-decrease)
(keymap-global-set "C-z"     #'undo-fu-only-undo) ;; suspend-frame
(keymap-global-set "C-S-z"   #'undo-fu-only-redo) 
(keymap-global-set "C-v"     #'yank) ;;  scroll-up
(keymap-global-set "C-x C-r" #'eval-print-last-sexp)
(keymap-global-set "C-s"     #'isearch-forward-regexp)
(keymap-global-set "C-r"     #'isearch-backward-regexp)
(keymap-global-set "C-M-r"   #'query-replace-regexp)
