By pressing sneak+use, you can cycle your inventory rows.
this means that if you want to have different hotbar presets to quickly switch between, such as a fighting row (swords, bow, shield etc.) and a farming row (hoe, seeds, water etc.) all you have to do to swich between those two is press sneak+use!
Hope this is helpful, enjoy!
side note, best technique is to hold sneak, and tap use.
Really cool
This mod is super useful, it avoids having to open your inventory all the time in construction, and in combat having an inventory full of weapons and being able to change them with just 1 keystroke is super practical. What's more, it looks like a new feature in ark ascended.
