Emacs使用笔记

修改配色

打开Emacs的配置文件。配置文件在~/.emacs。增加：

(set-background-color "black") ;; 使用黑色背景 (set-foreground-color "white") ;; 使用白色前景 (set-face-foreground 'region "green") ;; 区域前景颜色设为绿色 (set-face-background 'region "blue") ;; 区域背景色设为蓝色

尽管可以重启Emacs使配置生效，但更快捷的方式是在打开~/.emacs的时候执行命令M-x eval-buffer，就可以使配置文件立即生效。

快捷键

中文帮助：C-h t

撤消：C-x u C-/

启动自动折行模式：M-x auto-fill-mode <Return>

相关命令搜索（Command Apropos）：C-h a

Emacs 使用手册（manual）：C-h r

自动补全：M-/

在另一个窗口打开缓冲：C-x 4 b

复制：M-w

把当前进程放到后台（之后可用''fg''命令回到前台）： Ctrl Z

清屏：ctrl L

打开

终端模式：emacs -nw

;;在 LaTeX mode 中，默认开启 PDF mode，即默认使用 xelatex 直接生成 pdf 文 件，而不用每次用 'C-c C-t C-p' 进行切换。设置 'Tex-show-compilation' 为 t，在另一个窗口显示编译信息，对于错误的排除很方便。另外，编译时默认直接 保存文件，绑定补全符号到 TAB 键。
