What are some tips for golfing in Turing Machine But Way Worse, a language made by MilkyWay90 and ASCII-only?

Tips should be Turing Machine But Way Worse-specific and not be trivial (For examples that you shouldn't post, removing unnecessary whitespace or using shorter state names).

EDIT: Added documentation to TMBWW

Use the negative tape

For code-golf questions where you need to process input, it is easier to move onto the negative tape to push a bit to the tape instead of having to travel to the end of the input on the positive tape (and sometimes that way may even be impossible when you need to support NUL bytes).

For example, when you need to push to the tape and you have input, going on the negative tape would be much shorter than having to go to the end of the input.

0 0 0 0 1 0 0
1 0 1 0 1 0 0
0 1 0 0 2 1 1

would be much shorter than

0 0 0 1 1 0 0
1 0 1 1 0 0 0
0 1 0 1 2 0 0
1 1 1 1 0 0 0
0 2 0 1 3 0 0
1 2 1 1 0 0 0
0 3 0 1 4 0 0
1 3 1 1 0 0 0
0 4 0 1 5 0 0
1 4 1 1 0 0 0
0 5 0 1 6 0 0
1 5 1 1 0 0 0
0 6 0 1 7 0 0
1 6 1 1 0 0 0
0 7 0 1 8 0 0
1 7 1 1 0 0 0
0 8 0 0 9 0 0
0 9 1 0 a 1 1

and the second solution doesn't even work with NUL bytes.
