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.
