【问题描述】：
我正在尝试在 Linux 机器上运行的 TMUX 中创建新的箭头键绑定。我使用终端从我的 Mac (Mojave 10.14.6) SSH 到那台机器。这些都是我在~/.tmux.conf添加的组合：
# Use Shift-Arrow to move between panes
bind -T root C-Left select-pane -L
bind -T root C-Right select-pane -R
bind -T root C-Up select-pane -U
bind -T root C-Down select-pane -D
# Use Alt-Shift Left/Right to switch between tabs
bind -T root M-C-Left previous-window
bind -T root M-C-Right next-window
# Use Alt-Shift Up/Down to create/close a tab
bind -T root M-C-Up new-window
bind -T root M-C-Down kill-pane
它适用于 Ctrl+Left 和 Ctrl+Right，但不适用于其他。对于向上/向下箭头组合，它总是通过终端历史记录，所以我认为终端正在覆盖这些绑定。但是，我找不到这样做的地方，我从首选项-> 配置文件-> 键盘以及系统首选项-> 键盘-> 快捷方式中删除了所有相关组合。对于 M-C-Left/Right 没有任何反应。
我相信 TERM 变量设置正确：
TERM=xterm-256color
TERM_PROGRAM=Apple_Terminal
TERM_PROGRAM_VERSION=421.2
TERM_SESSION_ID=782B88DE-A8DA-4542-8428-F9D5C1EF6386
调用tmux list-keys 时也会列出键绑定。当按下 cat 中的组合时，我得到：
cat
^[[A (Ctrl+Up)
^[[B (Ctrl+Down)
^[^[[C (Ctrl+Option+Right)
^[^[[D (Ctrl+Option+Left)
^[^[[A (Ctrl+Option+Up)
^[^[[B (Ctrl+Down)
在 TMUX 服务器日志中，键绑定似乎已正确加载。启动 TMUX 然后尝试键绑定时的摘录：
