Command history in emacs shell mode
提问by Kris
In the bash shell, I can use the up arrow key to navigate to a previously entered command. But this does not work in emacs shell mode. Is there any way to enable this?
在 bash shell 中,我可以使用向上箭头键导航到以前输入的命令。但这在 emacs shell 模式下不起作用。有什么方法可以启用此功能吗?

M-p(and M-nfor the other direction) will do the trick.
M-p(M-n对于另一个方向)会起作用。
Here is the link to the Emacs manualon the subject.

C-pand C-nand C-rwork in (vanilla) bash too, along with some other emacs keys. Very handy.

In Gnu Emacs, the menu for the Shell mode is called "In/Out". (I think it also covers the more general mode called "comint".)
在 Gnu Emacs 中,Shell 模式的菜单称为“In/Out”。(我认为它还涵盖了称为“comint”的更通用的模式。)
