在 Alacritty 中逐字移动光标

Question

我最近开始使用 Alacritty，而不是 macOS 上的默认 Terminal.app。使用终端时，我可以使用 Option 和左右箭头键逐字跳转。在 Alacritty 中，此组合键导致

;3D

和

;2D

打印到屏幕上，而不是光标移动。

有没有办法配置 Alacritty 使用 Option 和箭头键逐字跳转？

Answer 1

使用 tmux 和 zsh，将它们添加到 alacritty 配置中：

key_bindings:
  ...
  - { key: Right, mods: Alt, chars: "\x1BF" }
  - { key: Left,  mods: Alt, chars: "\x1BB" }

Answer 2

自 alacritty 0.13.1 开始，不再支持 yaml 格式的配置，当前版本的 toml 也不支持

\x1B

。相反，请使用

\u001B

。

这是一个等效的例子c.f. @cfstras 的例子。配置文件现在也应该被称为

config.toml

而不是

config.yml

。

[keyboard]
bindings = [
  { key = "Right", mods = "Alt", chars = "\u001BF" },
  { key = "Left",  mods = "Alt", chars = "\u001BB" },
]

Answer 3

这是我的配置，它实现了 bash 环境中需要 alt 键的所有快捷键。

[keyboard]
bindings = [
  { key = "B", mods = "Alt", chars = "\u001BB" },  # Alt + B (Move backward one word)
  { key = "F", mods = "Alt", chars = "\u001BF" },  # Alt + F (Move forward one word)
  { key = "D", mods = "Alt", chars = "\u001BD" },  # Alt + D (Delete the word after the cursor)
  { key = "Backspace", mods = "Alt", chars = "\u001B\u007F" },  # Alt + Backspace (Delete word before cursor)
  { key = "U", mods = "Alt", chars = "\u001BU" },  # Alt + U (Uppercase from cursor to end of word)
  { key = "L", mods = "Alt", chars = "\u001BL" },  # Alt + L (Lowercase from cursor to end of word)
  { key = "C", mods = "Alt", chars = "\u001BC" },  # Alt + C (Capitalize the current word)
  { key = ".", mods = "Alt", chars = "\u001B." },  # Alt + . (Insert the last argument of previous command)
  { key = "Y", mods = "Alt", chars = "\u001BY" },  # Alt + Y (Yank the top of the kill-ring)
  { key = "/", mods = "Alt", chars = "\u001B/" },  # Alt + / (Attempt completion)
  { key = "T", mods = "Alt", chars = "\u001BT" },  # Alt + T (Transpose the words around cursor)
  { key = "R", mods = "Alt", chars = "\u001BR" },  # Alt + R (Recall the last command that matches input)
  { key = "N", mods = "Alt", chars = "\u001BN" },  # Alt + N (Search forward through history)
  { key = "P", mods = "Alt", chars = "\u001BP" },  # Alt + P (Search backward through history)
  { key = "Q", mods = "Alt", chars = "\u001BQ" }   # Alt + Q (Not a standard bash shortcut, customizable)
]
