If I correctly understand your question, you are searching for the Cross References feature in Hopper.
Cross References (or simply XREFs) is a feature of disassemblers to show you where certain functions and objects were called from or which functions and objects are used by a specific function. We can simplify it by relate to it as XREF-To and XREF-From. The referenced can be either Data or Code.
XREFs are a valuable resource when we want to figure out exactly where a function was called from or what functions the current function calls. This, as you understand, can be quite useful, so we don’t have to iterate the stack for frame pointers to look for the function that called the current function or alternatively searching by hand for a CALLs to specific addresses.
In hopper disassembler you can can see XREFs-To addresses by pressing X while you mark the desired address. XREFs-From can be shown using Alt+X. Alternatively you can find the Cross References lists under
Navigate in the Hopper's top toolbar.
You can also find the references to and from an adress by pressing Right Click on it and then choosing either "References to..." or "References from...".
Neverthless, when a program is analyzed, Hopper is adding a list of XREFs-From in the comments:
08048390 jmp dword [puts@GOT] ; puts@GOT,puts, CODE XREF=sub_8048662+15, sub_8048662+31, sub_8048662+86, sub_8048662+104
