元のポスターは、同じフレームで現在選択されているウィンドウをターゲットにすることを意味していると思います。元のポスターが別のフレームの特定のウィンドウをターゲットにしたい場合は、次の関連するスレッドで複雑な例を参照してください：https : //stackoverflow.com/questions/18346785/how-to-intercept-a-file-開く前に決定するフレーム
組み込み関数をコピーして、の代わりにを使用shellするという新しい関数を作成しました。この新しい関数は、ウィンドウでバッファを選択せずに、バッファを生成または検索します。shell-get-buffer-createwith-current-buffer ...pop-to-buffer*shell*
*shell*現在選択されているウィンドウにバッファを表示するには、次のコマンドを使用します。
(switch-to-buffer (shell-get-buffer-create))
または
(pop-to-buffer-same-window (shell-get-buffer-create))
または
(set-window-buffer (selected-window) (shell-get-buffer-create))
my-display-buffer左、右、上、または下の4方向に表示できるというカスタム関数を作成しました。3つの可能性があります：（1）フレームのウィンドウがすでにターゲットバッファーを表示している場合、同じウィンドウを再利用します。（2）選択したウィンドウに対して指定された方向にすでにウィンドウがある場合は、そのウィンドウにターゲットバッファーを表示します。（3）指定した方向にウィンドウがない場合は、その方向にウィンドウを作成し、そのウィンドウにターゲットバッファーを表示します。
使用例：
(my-display-buffer (shell-get-buffer-create) nil 'left)
または
(my-display-buffer (shell-get-buffer-create) nil 'right)
または
(my-display-buffer (shell-get-buffer-create) nil 'above)
または
(my-display-buffer (shell-get-buffer-create) nil 'below)
コード：
(require 'shell)
(defun shell-get-buffer-create (&optional buffer)
"Run an inferior shell, with I/O through BUFFER (which defaults to `*shell*').
Interactively, a prefix arg means to prompt for BUFFER.
If `default-directory' is a remote file name, it is also prompted
to change if called with a prefix arg.
If BUFFER exists but shell process is not running, make new shell.
If BUFFER exists and shell process is running, just switch to BUFFER.
Program used comes from variable `explicit-shell-file-name',
or (if that is nil) from the ESHELL environment variable,
or (if that is nil) from `shell-file-name'.
If a file `~/.emacs_SHELLNAME' exists, or `~/.emacs.d/init_SHELLNAME.sh',
it is given as initial input (but this may be lost, due to a timing
error, if the shell discards input when it starts up).
The buffer is put in Shell mode, giving commands for sending input
and controlling the subjobs of the shell. See `shell-mode'.
See also the variable `shell-prompt-pattern'.
To specify a coding system for converting non-ASCII characters
in the input and output to the shell, use \\[universal-coding-system-argument]
before \\[shell]. You can also specify this with \\[set-buffer-process-coding-system]
in the shell buffer, after you start the shell.
The default comes from `process-coding-system-alist' and
`default-process-coding-system'.
The shell file name (sans directories) is used to make a symbol name
such as `explicit-csh-args'. If that symbol is a variable,
its value is used as a list of arguments when invoking the shell.
Otherwise, one argument `-i' is passed to the shell.
\(Type \\[describe-mode] in the shell buffer for a list of commands.)"
