About this Mod
Hud Keys
Hud Keys is a lightweight "Quality of Life" client-side mod for Minecraft Fabric. It displays the keybind associated with each hotbar slot directly on the HUD, making it easier to track your controls and input.
👋 A Note from the Developer
This is my very first Minecraft mod! 🚀 I created this project to learn how to make mods and to solve a simple problem I had: wanting to see my hotbar keybinds clearly without cluttering the screen. Since I am just starting out, I would love to hear your feedback or suggestions. Thank you for checking it out!
✨ Features
Smart Overlays: Automatically reads your keybinds. If you bind Slot 1 to "Q", the HUD will show "Q".
Visual Feedback: The background of the key darkens and simulates a "click" animation when you press the button, giving you instant response.
Clean Design: Uses a minimalist style with rounded corners and outlined text, ensuring it is readable on top of any item (even bright ones like Gold Ingots).
Unobtrusive: The indicators are tucked into the corner of the slot so they never hide your items or durability bars.
Performance: Extremely lightweight and optimized to have zero impact on your FPS.

Hud Keys server crashes on startup – what to do?
Most common cause: wrong fabric version or insufficient RAM. Check the server log (latest.log) for "OutOfMemoryError" or "Mixin" errors. With Mado Hosting: ensure at least 3 GB RAM is allocated and the loader matches the mod version (1.21.11). You can switch loaders with one click in the panel.
Is Hud Keys compatible with fabric?

Server lagging with Hud Keys – how to optimize performance?
Recommended RAM: 4 GB (per 8 players). Use /spark profiler to check if Hud Keys consumes the most tick time. Common fixes: reduce server view-distance to 8-10, install "performant" or "starlight" as supplementary mods on Forge. With Mado Hosting, your server runs on NVMe SSDs with dedicated CPU cores for minimal latency.
