How to Use Zume Mod
Zooming In and Out
Zume Mod adds an advanced zoom to Minecraft that works differently from simple FOV-reduction mods. Instead of only shrinking your field of view, it gives you dedicated keys to control the zoom level while you are zoomed in.
To start zooming, press the Z key. While zoomed, press = to zoom in further and - to zoom out. This lets you fine-tune how close distant objects appear without leaving the zoomed state.
All of these keybinds can be changed to your liking in the standard controls menu, so you are not stuck with the defaults if they conflict with other mods or your own preferences.
That is the whole mod: press Z to zoom, then use = and - to adjust. No items, blocks, or recipes are involved.
