Rather than introduce too many new keybinds into the game for ammo switching, PPC field inhibitors, ECM mode or AMS toggle, why not just implement all these functions as a special sort of toggle, configurable through weapon groups?
Just as we have the ability to add or remove weapons from weapon groups using arrow keys + the weapon group toggle key, I propose that another "function toggle key" be added, allowing players to add mode switches for items to weapon groups as well. Here's a picture:

In the above picture, each PPC can toggle it's field inhibitor via weapon groups 4 and 5, while weapon group 6 toggles ammo type for the C-LB 10-X AC. Probably not a realistic setup, but it gets the idea across (please bear with the mixed tech). The brighter yellow-ish group assignments are the fire groups that we have now. Also note that the weapons with a toggle have a small dot before their names in the same blue hue to let players know that some kind of functionality exists.
Not shown in the image: I propose that ECM disrupt/counter and AMS active/inactive also be configurable in this way, freeing up valuable keyboard space for players who don't need one or both of these features.
Also, I would propose that more weapon groups be added to account for the extra features tacked onto the weapon group system; maybe a number that the player can increase or decrease in their settings menu?
That's it... what do you all think?
