This mod was built for fabric 1.20.4

It allows you to set 3 keybinds in the keybind settings of you game under the tab - BlockCoords -

The keybinds do the following things :

 - Copy the block coordinate of the block you are looking at

 - Copy the block's id (ex : redstone_block)

 - Copy the block's coordinate and id

The mod also has a french lang file if you really can't find the keybinds and don't understand a word of english but the how are you even reading that.
