VSCode Tmux Keybinding

[VS Code Marketplace] [Open VSX Registry]

This is a simple extension for tmux behavior in the VS Code terminal. It provides keybindings similar to tmux, using either Ctrl+B (default) or Ctrl+A as a prefix.

Configuration

You can configure which prefix key to use in your VS Code settings (settings.json):

{
  // Enable keybindings that use Ctrl+B as a prefix (default: true)
  "tmuxKeybinding.enableCtrlBPrefix": true,

  // Enable keybindings that use Ctrl+A as a prefix (default: false)
  "tmuxKeybinding.enableCtrlAPrefix": false
}

Keybinding

All keybindings are active only when the terminal has focus (terminalFocus).

General Bindings

`ctrl+k`	`workbench.action.terminal.clear`	Clear terminal
