Also, just for the record, here is why it is impossible to use hotbar #1:

(1) Turn off all of the automated hotbar settings. In theory, this should prevent the game from moving things around on you and messing up your hotbar setup. (Spoiler: it doesn't.)

(2) Click the lock icon next to the hotbar until it is locked. Logically speaking, locking the hotbar should prevent things from being moved around and messed up. (It doesn't.)

(3) Add a bedroll to your inventory. Watch the game add a bedroll icon to the hotbar, despite (1) and (2) above.

(4) Throw the bedroll on the ground. Pick it up again. Now you have two bedroll icons on your hotbar.

(5) Bang head against desk. Curse some unknown game designer's stupidity. Drag the pointless bedroll icons off the hotbar.

(6) Save the game.

(7) Reload the game you just saved.

(8) Now, in the place where you previously removed the bedroll icons from the hotbar, you will have the icon for the skill "Sucker Punch." Or at least I do. Even though my character doesn't even know the skill "Sucker Punch."

(9) Hover the cursor over the "Sucker Punch" icon. The tooltip reads "Bedroll."

(10) Bang head against desk.

(11) Drag the "Sucker Punch" icon off the hotbar as much as you want. Every time you reload a save game it will be back again, still labeled as "Bedroll." Sometimes it may have moved to another location on the hotbar. It is likely surrounded by another pile of bedrolls and other random junk that the game has automatically added.

(12) Switch to hotbar #5 and put your icons there, so that you will have at least a little bit less insanity to deal with.

Hotbars are broken. I don't know who in the world thought automated hotbar activity could possibly be a good idea in the first place. Whatever the case may be, the reality is that they are broken. They need to be fixed. Simply eliminate all the automated hotbar routines.
