That instruction is defined as a function usually. (mathpix-app-id "app_id") Because the function `mathpix-app-pid' does not exist, there is error. Instead, what you need most probably is: (setq mathpix-app-id "app_id") as then the instruction `set' or "Set quoted" means to assign the value "app_id" to variable `mathpix-app-id'. -- Jean Take action in Free Software Foundation campaigns: https://www.fsf.org/campaigns In support of Richard M.
