The Custom Comments plugin provides a flexible way to insert personalized comment markers into your notes using keyboard shortcuts. Instead of being limited to built-in HTML or Markdown comment styles, you can define your own templates with {cursor} as a placeholder to control where the cursor lands after insertion. The plugin supports multiple marker sets, each with its own toggle and command, allowing you to maintain different types of comment formats for different contexts. It also offers a word-only mode that quickly toggles comments for a single word at the cursor position. For advanced setups, you can reload marker commands without restarting the plugin, making it easier to experiment with multiple formats.
