@zipster1967, you can only edit them using the TRIGGERcmd agent installed on your computer. You can't edit them on the website.
If you run Windows, you should have a "tray" icon in the lower-right near your clock. You can right-click that, then click "GUI Command Editor". Then click the pencil next to the commands you want to edit. Please confirm you've gotten that far.
The background commands are added/removed by the background service. The foreground commands are added by the foreground agent. That tray icon is part of the foreground agent.
