  • Clear selection: Clears the map view chunk selection.

  • Export chunks to ZIP: Opens a 'Save As' dialog box to export the selected chunks as region files containing the chunks to a ZIP archive.

  • Export view to PNG: Opens a 'Save As' dialog box to export the current map view as a PNG file.

  • Delete selected chunks: Displays a confirmation prompt for the user to delete the selected chunks from the currently-loaded world. (Chunks can be re-generated by Minecraft, but all user-created data in the chunks will be lost. It is a good idea to keep a backup of your world before performing this action.)
