Skip Forward and Back in a Carve

I often have experienced interrupted carves for a variety of reasons,
using Gcode generated in Fusion and imported into easel for carving on an x-carve 1k.
I wrote a post about one such experience here:

the solution I came up with, editing the gcode using a text editor, relies on your ability to access the the gcode. By definition you do if you are importing as you have to generate a file to import.
I have never looked to see if easel writes the gocde it is using anywhere accessable.
If ti did, this is an obvious avenue to explore: copy the file, edit it, and import it…
