Tool Bar

Summary
The Tool Bar, also known as Tool Circle, is where you can equip or unequip items/weapons/tools into your inventory. You can't always equip all types of items since they don't either fit or it's not right to put into the inside of the Tool Bar.

To open the Tool Bar, simply hold the Tab button until a large-size circle appears in the middle of your screen.

To equip an item, simply open your inventory (by pressing G) and finding the item you want to apply, then hold E until you've equipped it into your tool bar.

You can't equip food/deployable/storage/resources into your tool bar.
