Spacemacs Rocks Note Day 2

2017-10-23

A series of notes that I learn Emacs hacking. Change variable globally, disabling auto-save and auto-backup; `require` keyword, enabling recent files opening, enabling delete selection mode; code block and example block fast typing; initializing Emacs with full screen; showing matching parenthesis, highlighting current line; package management system configuration; adding a new theme, hundgry delete mode, swiper, smartparens; customize-group; ordered list in org-mode; JavaScript IDE in Emacs; setting schedule in org-mode.

setq vs. setq-default
