The problem with RPG's short names was not that the opcodes had short

I don't mind that "setll" is not written as "setLowerLimit".

This is absolutely true. I am still not sure I agree with your
particular choices for the data structure you're working on, but I
definitely agree with the principle that keywords should be on the
short side.

I don't know what is a "normal" map but i believe that a map with multiple
values per key is indeed called a multimap.

A normal map has unique, hashable keys. Thus lookup, insertion, and
deletion are all O(1). Generally ordering of the keys is not
guaranteed, because it's more important that the hash work well. This
is a primary, fundamental data structure in many languages as it is
extremely fast and extremely flexible.

However, in my case, the map is simply storing multiple key/item pairs
having the same key, so the same key is simply stored more than once.

In languages that have a regular map, a multimap is simply a regular
map whose values are collections. There is no separate implementation
for multimap.
