C-d 消除右边得一个字符
C-o open the new line
C-k 删除后面的所有字符
Here are the details for using C-o . If you are at the beginning of a line, C-o
creates a new, empty line above the current line. If you are at the end of a line, C-o
creates a new, empty line below the current line. If you are within a line, C-o breaks it
into two separate lines
To insert one of these characters into your text, first press C-q . This tells Emacs
that the next character is to be taken literally. (Think of the q as meaning “quote”; that
is, to take the next key you type literally.) Thus, to insert a
C-q C-c . To insert a
C-x BS delete from the current position, backwards, to the beginning of the sentence.(从当前点删到尾)

buffer
C-x b When you press C-x b , Emacs will wait for you to enter the name of the buffer with
which you want to work. If this buffer already exists, Emacs will just move it into the
window. Otherwise, Emacs will create a brand new empty buffer in the window using
the name you specified. Thus, C-x b is the command to use when you want to create a
new buffer.
C-x 4 b tells Emacs to display whichever buffer you specify in a different window
C-x 4 C-o command. This is similar to the C-x 4 b command, except that the selected window does not change
