What is the shortcut key to comment on an issue in Jira?

The shortcut key to comment on an issue in Jira is represented by the letter 'm'. This key provides a quick and efficient way for users to add comments without needing to navigate through multiple menus. Utilizing keyboard shortcuts like this enhances productivity, allowing team members to communicate effectively about issues in real time.

The other choices do not correspond to the function of commenting on an issue in Jira. Each key has its specific function or shortcut assigned within the application, but 'm' is specifically designed for commenting, making it the correct option for facilitating quick discussions on issues.
