If anyone needs translation from Russian:
The way this works is a g-code filter, which generates a "reverse"
g-code for a particular g-code line and inserts it _before_ this
particular g-code line with a "/" symbol in front of it.
It seems like a change in Axis GUI script to redefine "zoom-in" and
"zoom-out" buttons, so that it starts taking into account all the
lines with "/" symbol in front of it, when asked to reverse.

A little comment from me:
It is obvious that this approach can easily reverse _current_ line
being executed. But it is not clear to me, how to back up more than
one line - it might be necessary if the code consists of really tiny
G1 moves.
