### General Information on user-defined Tools

User-defined Tools are external applications that can be added via Options \> Tools to work directly from Mp3tag's main window via the context-menu of the file view (find more about this feature in the corresponding [help topic](https://docs.mp3tag.de/customization/options/tools).

You can also use the keyboard shortcuts Ctrl+1, Ctrl+2 to Ctrl+0 to trigger the first, second to tenth user-defined Tool on the selected files.

Parameters like `%_path%` should be in quotation marks, so paths and filenames with spaces are passed properly. An example of this would be `Parameter1 Parameter2 "%_path%"`
