I have been working with R for a while, yet I am unable to find out how to quit or select the relevant package in Help options prompt when a function is in multiple packages

Here is an example:

> ?grep
Help on topic ‘grep’ was found in the following packages:

  Package               Library
  BiocGenerics          /Library/Frameworks/R.framework/Versions/4.2/Resources/library
  base                  /Library/Frameworks/R.framework/Resources/library

Tried several options including Ctrl^C yet R is not quitting the prompt.

I found the following question, and understand the way to seek help from a specific package but it does not answer my question.

How to specify the package when looking up a help reference page for a function?
