ok i got everything else. but is there a way where you can use space bar as an on and off button for speed instead of having to hold it to have speed and when you let go it becomes normal again?

No.

or..

Leave a control remote or something over the speed button

You do not need to make two separate threads that regard the same topic.

Try VBA-M. Perhaps mudlord and co. have implemented the feature you want in the SVN builds. Or not.
