Key Holder

Ever needed to hold down a key for a while — forward to walk into a wall, space to keep jumping, your sprint key, a macro-bound key from another mod — without actually holding it? Key Holder does it for you.

Pick any key or mouse button and toggle it "held." Key Holder simulates that key being pressed every tick until you turn it off, exactly as if you were holding it down yourself.

Features

• Pick any key — keyboard or mouse, via a chat command or a click-to-capture config field
• One-button toggle — bind "Toggle Key Hold" in Controls to start/stop instantly, no typing required
• Chat commands for quick or scripted use
• Mod Menu integration — a Cloth Config screen if you'd rather click than type
• Client-side only — no server install needed, safe for any server (single-player and multiplayer alike)

Commands

Command	What it does
/keyholder set <key>	Choose the key to hold — e.g. w, space, key.mouse.left
/keyholder on	Start holding the configured key
/keyholder off	Stop holding it
/keyholder toggle	Flip it on/off
/keyholder status	Show whether it's active and which key is set

• Fabric Loader 0.18.4+
• Fabric API
• Optional: Mod Menu + Cloth Config for the in-game config screen
