after opening whatever container(s) you are wanting to change, then push....

"(shift) + (~/`) ( both tild and backquote are the same key)" ie.. pushing shift and ~ keys, "at the same time".

a popup menu comes up, showing "container selection(s)" and a list of current "containers" to choose from.

choose one and a new popup menu opens, asking for "width +1/-1 and height +1/-1, choose and it changes instantly.

tdlr: me opening the menu's to change the size of the "shipping container" and making it 2 squares wider.


only option i didnt see work, was the "tool belt option" (didnt seem to do anything?), the rest worked, ie.. purse, pouches, storage chest(s) (sturdy, box, shipping, delivery, ect..), , mailbox (post), ect.. as far as i have tried.

it only mentioned the "backquote" portion in mod description, though "tild" key is more known, but i dont know where you got the key combos you mentioned.

good luck, have fun and a nice day
