TLDR: keyboard combination <C-c '> that should be formatted as `C-c '` is instead formatted as `C-c '' (double single quotes instead of single quote and backtick). I observe it in Info Manual of Org Mode Compact Guide ch. 11.4, 12.4.
I know this is a very minor issue (should I even call it one?:)) but nevertheless think it is better to report than not.
On a side note, I took a quick look at
org-guide.org and it seems that <
{{{kbd(C-c ')}}}
> is the culprit. But I'm quite a novice in both Emacs and Org Mode so don't how to tackle this problem.
