はじめに

Linux 上であれば Emacs でシェルを操作したいが、
各種事情により Emacs を導入できない場合の代替手段として tmux 2.6 を使う.

tmux はバージョンが更新されると、過去の設定が動かなくなるので、
私は 2.6 で固定して使っている.

色々と参考にさせてもらった御礼の意味をこめて、次の emacs 操作風の設定を記しておく.
本項では 「tmux 2.6」における Emacs キー操作の $HOME/.tmux.conf を記す.

環境

DISTRIB_ID=Ubuntu
DISTRIB_RELEASE=18.04
DISTRIB_CODENAME=bionic
DISTRIB_DESCRIPTION="Ubuntu 18.04.4 LTS"

事前準備

システムに xclip をインストールしておくこと

tmux 2.6 の状態

tmux を起動させた状態で C-x ? を実行した結果である
