I use these Marzipan rules a lot in my sessions. The only thing the 'k' key does is bring up the main control panel. This lists links to pop-up info panels that you have set up in the Session (there are 4 panels available. They provide information on the real-time status of consists, train locations, industries and product queues).
From experience I say the following;
- it's script based, so unlikely that you can change it
- it works for TRS2004, not sure about later versions of Trainz
- all your trains, products and industries have to be present and in working order, otherwise you get stack-dump errors.
- sometimes the control panel is slow to display all the links. In that case, I have found that clicking the X forces the links to display one by one. If they are all displayed, then clicking the X closes the control panel.
I hope that answers the original question, whatever it was.
