- Opus Raw Commands
- External Command Control Codes
It’s actually an extensive system of providing parameters to the internal/external commands of the file manager. The parameters are implemented quite sophisticated and extend beyond our "common perception" of command-prompt parameters since they include a powerful form similar to macros and scripting (one of my favorite feature suggestion http://www.ghisler.ch/board/viewtopic.php?t=119 ).
You can download the manual of Opus in pdf here http://www.gpsoft.com.au/Download.html and have a look at the corresponding sections. It would be great if TC could follow a similar system and it would be actually a first step to an advanced macro system in the future too! (fingers crossed

Please, Christian have a look at the aforementioned pdf file as what’s included can be useful to you if you are planning to implement something similar for TC in the future.
Kind regards,
