The subject in question is a “caret”. It’s also known by the more generic word cursor (or slightly more specific “text cursor”) but seeing as there’s a specific word for the item in question it makes sense to use that, even if both are appropriate. They’re all a kind of symbol so we could just call it that. But that’s even less helpful, isn’t it.
It’s called a symbol.
Never seen that used in this context, but I’m sure it has lots of names.
The original patent is on cursor though. https://patents.google.com/patent/US3531796
Which is the same as the marker on a slide ruler was called.
