Tooltip

A tooltip is a text box that appears next to the mouse cursor when hovering over certain elements in the user interfaces, or when switching the held item.

Item tooltips
When hovering over an item in the inventory with the mouse cursor, a tooltip with the item’s name will appear next to the cursor. Some items display extra information on their tooltips.

Held item tooltips
When switching the item being held, the name of the item appears above the hotbar. In Bedrock Edition, held item tooltips also show enchantments and shulker box contents.

Effect tooltips
When effects are visible in the compact style, hovering over an effect icon displays more information about the effect.

Option tooltips
When certain options are hovered over, they show a description in the form of a tooltip.

Trivia
The old tooltip design can still be seen on the “Items” section of the statistics menu.
