在看文档的时候,这里有点疑问
C-j at the end of s-expression prints the result in the scratch buffer.
但是我试了一下,只是换行而已,查一下帮助文档
C-j runs the command electric-newline-and-maybe-indent (found in
global-map), which is an interactive compiled Lisp function in
‘electric.el’.
It is bound to C-j.
(electric-newline-and-maybe-indent)
Insert a newline.
If ‘electric-indent-mode’ is enabled, that’s that, but if it
is *disabled* then additionally indent according to major mode.
Indentation is done using the value of ‘indent-line-function’.
In programming language modes, this is the same as TAB.
In some text modes, where TAB inserts a tab, this command indents to the
column specified by the function ‘current-left-margin’.

我不知道这有什么误解,请帮我看看
