Vertical Scroll

 --- Vertical Scroll Hold a modifier key and scroll to cycle items through the vertical column of your selected hotbar slot, no more opening your inventory just to swap what's in hand. How it works Each hotbar slot has a "column", the three inventory slots directly above it. While holding the modifier key (default: Left Alt), scrolling rotates items through that column: - Scroll up, brings the top item down to your hotbar - Scroll down, brings the bottom item up to your hotbar The hotbar selection stays put; only the items move. HUD overlay While the modifier key is held, a small overlay appears above your selected hotbar slot showing the three column slots with their items and stack counts. Arrows (▲ / ▼) indicate which end of the column will cycle to hand. Details - Modifier key is rebindable, find it under Controls → Vertical Scroll - Client-side only, works on any server, no server-side install needed - Supports Minecraft 1.21 and above, including all 1.21.x releases and 26.1
