CopyBlockId

CopyBlockId is a lightweight client-side utility mod for Minecraft 1.20.1, 1.21.1 on Fabric, Forge, and NeoForge. Press Ctrl+C to copy registry IDs directly from Minecraft without digging through debug screens, configs, or command output.

What It Copies

• The block ID you are currently looking at, if enabled in the client config
• The entity ID you are currently looking at, if enabled in the client config
• The item ID of the hovered inventory slot
• Hovered item and fluid IDs from JEI and REI overlays/tooltips

Example clipboard output:

minecraft:dirt

When a value is copied, the mod shows a short in-game notification.

Why It Is Useful

• Modpack development
• KubeJS and datapack scripting
• Commands and config editing
• Quick registry lookups while testing

Controls

• Ctrl+C while looking at an entity: copies the targeted entity ID when copyTargetedEntityInWorld is enabled
• Ctrl+C in the world: copies the targeted block ID when copyTargetedBlockInWorld is enabled
• Ctrl+C over an inventory slot: copies the hovered item ID
• Ctrl+C over JEI or REI entries: copies the hovered ingredient ID

The shortcut is ignored while typing in chat or focused text fields.

Config

CopyBlockId creates a client config:

• Fabric: config/copyblockid-client.properties

• Forge/NeoForge: config/copyblockid-client.toml

• copyTargetedBlockInWorld = false by default. Set it to true to allow Ctrl+C in the world to copy the ID of the block you are looking at

• copyTargetedEntityInWorld = false by default. Set it to true to allow Ctrl+C in the world to copy the ID of the entity you are looking at
