ZenScroll

With ZenScroll, modpack authors can use CraftTweaker to create "scroll groups". You can cycle between items in a scroll group by holding down the modifier key (default ALT) and scrolling the mouse wheel.

To learn more about how to create scroll groups, check my Github readme. Here are a few examples:

import mods.zenscroll.ZenScroll;

ZenScroll.add(<minecraft:apple>, <minecraft:gravel>, <minecraft:dirt>);
ZenScroll.add(<minecraft:wool:*>);
ZenScroll.add(<minecraft:stained_hardened_clay:*>);

But wait, there's more:

var glasses = ScrollGroup.of(<minecraft:stained_glass:*>, <minecraft:stained_glass_pane:*>);
glasses.copyTag(); //retain any nbt tags when you scroll
ZenScroll.add(glasses);

//scroll apples into cookies but not the other way around (contrived example :D)
ZenScroll.add(<minecraft:apple>).processor(
  function(prev as IItemStack, next as IItemStack) {
    return <minecraft:cookie>;
  }
)
