I am using the Emacs editor, and every time I start Emacs, I lose my previous settings.
For example, every time I have to type:
cua-mode
RETauto-complete-mode
RETHow can I save my settings in Emacs?
Thanks.
The best answer I can think of is to point you at the manual:
http://www.gnu.org/software/emacs/manual/html_node/emacs/Customization.html
In particular, see the sections on "Easy Customization" and the "Init File"; but I would recommend at least skimming over everything in this section.
