How to replace specific numbers based on letter adjacency in Gcode

[Myceliuman]

I am trying to replace E3 with E0 at the designated indeces found in the blue group. I have lines in the Gcode that I don’t want to extrude at. I am looking for a command similar to control F, replace E3 w/ E0.

Adding text into gcode

That wasn’t so hard, eh? Much easier than creating test data by hand [Adding text into gcode_2023Oct3a] Adding text into gcode_2023Oct3a.gh (19.6 KB)

Sequentially number specific lines in list

This looks easy but it wasn’t. Though I started with code from @Volker_Rakow, I replaced everything because I wanted it to be easy to add more keywords to be numbered. This image shows three words in a text panel connected to TMatch (upper left). More can be added easily.
