如果你在当前活动缓冲区中打开了.emacs文件:

M-x eval-buffer

M-x load-file
~/.emacs

我目前使用的是Ubuntu 15.04 (Vivid Vervet);我喜欢为它定义一个键。

[M-insert]在我的键盘上翻译成Alt + Ins。

把这个放在你的emacs文件中:

(global-set-key [M-insert] '(lambda() (interactive) (load-file "~/.emacs")))

如果你碰巧在Emacs内部打开了一个shell，你还可以这样做:

. ~/.emacs

这样可以节省一些按键。

这里有一个快速和简单的方法来快速测试您的配置。您还可以在特定的lisp末尾使用C-x C-e来单独执行某些函数。

C-x C-e runs the command eval-last-sexp (found in global-map), which is an interactive compiled Lisp function. It is bound to C-x C-e. (eval-last-sexp EVAL-LAST-SEXP-ARG-INTERNAL) Evaluate sexp before point; print value in the echo area. Interactively, with prefix argument, print output into current buffer. Normally, this function truncates long output according to the value of the variables ‘eval-expression-print-length’ and ‘eval-expression-print-level’. With a prefix argument of zero, however, there is no such truncation. Such a prefix argument also causes integers to be printed in several additional formats (octal, hexadecimal, and character). If ‘eval-expression-debug-on-error’ is non-nil, which is the default, this command arranges for all errors to enter the debugger.

其他人已经回答了你的问题，但我发现我通常想执行我刚刚写的行。

为此，Elisp部分的Ctrl + Alt + X工作得很好。
