How to Cycle Villager Trades with the GUI Button

Open the trade screen and find the button

Walk up to any villager that has a profession and open its trading GUI like normal. The Trade Cycling Mod adds a small button somewhere on the trading screen — by default it sits near the trade list, but its exact position depends on your configuration. Look for an icon that suggests refreshing or swapping, not the vanilla trade arrows.

Cycle until you see the offer you want

Click the cycling button once and the villager's current offers are rerolled on the spot. Keep clicking until the trade list shows the item you are hunting for, such as a specific enchanted book, a good emerald price, or a useful map trade.

Confirm and lock in the trade

Once the offer you want appears, complete at least one trade with the villager. This locks that trade into the villager's memory so it will not be lost when offers refresh later. If you accidentally cycle past a good trade, you can keep cycling — the mod does not consume the trade, it simply rerolls the list. Remember that cycling changes all current offers, so decide which trade matters most before you commit. If the button is in an awkward spot, open the mod's config screen and move it to a corner that does not overlap the trade list.
