The script command "cmd" for sending system command has been fixed to work with the new console. I've also updated the guide text because some of the syntax was incorrect. The correct syntax is:
keys=cmd % "C:\Program Files\VideoLAN\VLC\vlc" --qt-start-minimized --play-and-exit C:\soundfile.mp3
You can now use the left/right arrows to move the cursor back and forth within the console's input text. This allows you to edit anywhere in the input text rather than having to delete everything up to the point you want to edit. You can also right-click to copy individual words or numbers.
These changes require Speeder version 154+.
