This keybind has three issues:

1. the use of the shift+key isn't obvious to people via the controls menu or the item tooltips, so you have to look it up as evidenced by other "issues".
2. The keybind isn't properly context sensitive, so folks like me that like to map "ALL" mods' tool mode change key to V find that it doesn't work for ANY tools until mekanism's is remapped.
3. AFAIK it's not needed at all. Please correct me if I'm wrong, but applying a default of shift+ scroll wheel context mode change like what's been done to the configurator should work for the bow and everything else right?

I'd like to suggest removing the keybind entirely. Instead using Shift + scroll while holding tools to change their mode. If that's not ideal, please at least make the keybind context sensitive and allow conflicting keybinds to work. It would also be nice if mode changing was controlled similarly for all tools/weapons and clearly explained in tooltips.

using Mekanism-1.12.2-9.8.2.389. Pardon me if this has already been addressed.

Some of that stuff does certainly seem like a good idea, going to throw a 1.15 tag on it so it is easier for me to remember to look at it, as we currently aren't really working on the 1.12 branch but as an enhancement it certainly is still valid for the 1.15 branch.
