Access the material list in-game

[djmattyg007]

I'd like for there to be a way to access the material list in game, so that I can automate collection of the necessary materials. I'm currently playing FTB Skies for Minecraft 1.19, with Refined Storage, Integrated Dynamics, etc. I was hoping that I could place my copy+paste gadget (or perhaps a building template) into a chest, read the contents of the current template, and dump the required items into a chest from my storage system.

The wiki seems to indicate that it is possible to access this list in-game, but I haven't been able to work out how to do it.

You can press M whilst holding a template or a copy paste gadget to see the in-game material list
