[ATM8] How to change cycle tool tip key binds on Silent Gear

I might just be stupid but I've looked through all the key binds and both the config files. When looking at the material details on hover and holding ctrl, you see the details for the material as a main part. This is when I should be able to press 'c' or 'z' to then see the details on using that material as a tool rod, tip, etc.

But 'z' and 'c' aren't working and I can't figure it out. Please help if you know how!
