How do I change my Jira task’s status? (e.g., from To Do to In Progress)

The fastest way is to right-click the worklog and select your desired status directly from the status menu! You can also update it in the main work item editing window.

The status menu conveniently displays the task’s current status at a glance. If you need to update other task details alongside the status, opening the editing window gives you full access.
