This mod allows you to select any item from your entire inventory, not just your hotbar.
When you are equipped with this item:
Press and hold the configured hotkey to open your inventory on-screen.
Move your mouse to highlight the item you want.
Release the hotkey to place the selected item into your "right hand".
What's even more satisfying:
Perfect block picking experience You can use the middle key to pick the block and open the ui at the same time,
then your mouse will automatically move onto what you are looking at. This function is turned on by default.
