【问题描述】：

我是 tmux 用户，个人更喜欢使用 alt+arrow 的切换窗格。但是，在 vscode 中，它不起作用。即使我尝试删除默认键绑定以防止重叠。

我尝试绑定到alt+u/h/j/k，它工作正常。我认为vscode中的alt+arrow键绑定有问题。是否有任何设置我没有找到或者它是一个错误？

keybinding.json - vscode

 
        "key": "alt+up",
        "command": "-workbench.action.terminal.focusPreviousPane",
        "when": "terminalFocus"
    ,
    
        "key": "alt+down",
        "command": "-workbench.action.terminal.focusNextPane",
        "when": "terminalFocus"
    ,
    
        "key": "alt+left",
        "command": "-workbench.action.terminal.focusPreviousPane",
        "when": "terminalFocus"
    ,
    
        "key": "alt+right",
        "command": "-workbench.action.terminal.focusNextPane",
        "when": "terminalFocus"
    

.tmux.conf

# switch panes with "(alt) + (↑ ↓ ← →)"
## This does not work in vscode integrated terminal
bind -n M-Up select-pane -U
bind -n M-Down select-pane -D
bind -n M-Left select-pane -L
bind -n M-Right select-pane -R

## This do work
bind -n M-u select-pane -U
bind -n M-j select-pane -D
bind -n M-h select-pane -L
bind -n M-k select-pane -R

【参考方案1】：

when 子句已更改，因此这些键绑定实际上并未被删除。您可以通过将日志级别更改为 trace 并查看 devtools 控制台来检查这一点。

忽略这些键绑定的更好方法是通过此设置将它们从优先于向 shell 发送序列中删除：

  "terminal.integrated.commandsToSkipShell": [
    "-workbench.action.terminal.focusPreviousPane",
    "-workbench.action.terminal.focusNextPane",
    "-workbench.action.terminal.focusPreviousPane",
    "-workbench.action.terminal.focusNextPane",
  ],

【参考方案2】：

[
  
    "key": "alt+up",
    "command": "workbench.action.terminal.sendSequence",
    "args":  "text": "\u001b[1;3A" ,
    "when": "terminalFocus"
  ,
  
    "key": "alt+down",
    "command": "workbench.action.terminal.sendSequence",
    "args":  "text": "\u001b[1;3B" ,
    "when": "terminalFocus"
  ,
  
    "key": "alt+left",
    "command": "workbench.action.terminal.sendSequence",
    "args":  "text": "\u001b[1;3D" ,
    "when": "terminalFocus"
  ,
  
    "key": "alt+right",
    "command": "workbench.action.terminal.sendSequence",
    "args":  "text": "\u001b[1;3C" ,
    "when": "terminalFocus"
  
]

除了上面丹尼尔的回答之外，xterm.js在按下alt + left时的默认行为是向后跳一个单词，就像ctrl + left一样（右同）。 为了让alt + left发送正确的序列tmux需要，你必须将上面两个键绑定添加到keybindings.json
