Sublime Text Duplicate for VSCode

Mirrors Sublime Text's duplicate behavior in VS Code:

• With selection — duplicates the selected text inline
• Without selection — duplicates the entire current line
• Supports multiple cursors/selections simultaneously

Usage

Press ⌘+Shift+D (Mac) or Ctrl+Shift+D (Windows/Linux) to duplicate text.

You can also run it from the command palette (⌘+Shift+P / Ctrl+Shift+P): search for Sublime Duplicate Text.

Keybindings

This extension registers the following shortcut automatically:

[
  {
    "mac": "cmd+shift+d",
    "key": "ctrl+shift+d",
    "command": "sublime-duplicate-text.duplicateText",
    "when": "editorTextFocus"
  }
]
