Dual Hotbars Mod for Minecraft 1.9/1.8.9/1.7.10

This mod gives you a 18 slot hot bar. By default this is rendered as two rows of 9, but can be changed in the config to be 1 row of 18. The upper slot is taken from your top row of inventory items.

There are 3 ways to select an item in the 9 new slots:

Scroll the mouse wheel.
Double tap the number key for the slot below it (i.e. double tap ‘1’ for 10th slot).
Hold a modifier key while pressing the number key (ctrl by default).
