Which of the following actions is supported in Google Keep?

Adding audio recordings to notes is a feature supported in Google Keep. This functionality enhances the note-taking experience by allowing users to record their thoughts or ideas in an audio format, which is particularly useful for capturing information quickly when typing may not be feasible. By integrating audio recordings, Google Keep provides a more versatile approach to note-taking, accommodating different preferences and needs of users.

In contrast, creating spreadsheets from notes is not a function of Google Keep — the platform focuses on simple note-taking rather than complex data management. Writing code snippets in notes is also not a standard feature of Google Keep, as the application is designed for more general note-taking instead of specialized coding tools. Lastly, while sharing notes is possible, sharing with non-Google users has limitations, primarily as it often requires all users to have a Google account to collaborate effectively, which makes it less inclusive for those outside the Google ecosystem.
