Show Hidden Tooltip Details Only When Holding Shift

Mark Lines as Hidden

Use the hidden property to keep certain tooltip lines invisible until the player presses Shift:

`json

{

"match": "minecraft:enchanted_book",

"lines": [

{

"text": "Enchanted Book"

},

{

"text": "Hold Shift for details",

"color": "#AAAAAA"

},

{

"text": "Enchantment: Sharpness V",

"hidden": true

},

{

"text": "Rarity: Legendary",

"hidden": true

}

]

}

`

Configure the Keybind

By default, Left Shift reveals hidden lines. This keybind is typically configurable in the mod settings.

Test the Behavior

Reload with F3 + T. Hover over the item normally to see only visible lines. Then hold Shift while hovering to reveal the hidden details.
