To submit changes after typing a comment in a spreadsheet cell, which action is necessary?

When entering or editing comments in a spreadsheet, particularly in collaborative tools like Google Sheets or Microsoft Excel, submitting the changes typically requires a specific action to ensure that the comment is properly saved and shared with others.

Clicking the Post button is the correct action because it explicitly indicates your intention to finalize and submit the changes made to the comment. This functionality is standard in applications that allow for comment additions, ensuring clarity and confirmation of the changes you have made. Once the Post button is clicked, the comment becomes part of the document, allowing others to view and respond to it if necessary.

In contrast, actions like clicking the Save button or hitting the Enter key may pertain to saving the entire document or concluding a cell edit rather than specifically submitting a comment. The Esc key generally cancels the comment editing process without saving any changes made. Hence, the Post button serves as the definitive action for submitting comments.
