I'm new to Emacs. How do I customize a setting?
This is actually a generic question inspired by the org-mode manual:
In this description, it says to (setq org-clock-persist 'history). Where should I set this?
I'm a new user to Emacs, and I'm starting with org-mode. If I need to set this in the .emacs file, I do not know how to locate it and do it.
Step by step guidance would be helpful.
