To get started, enter start and end times and press the “Start timer” button. You can click on the small clock icon to set the times easily.

Click on the “+” button to add a new correction or clarification comment. You can then type the text you want and press Enter to display it in formatted form.

Comment text is entered as HTML, so you can add formatting with tags such as <b>...</b>. You can also use LaTeX notation in your comments, by wrapping text in \(...\), e.g., \(x^2 + y^2\) produces \(x^2 + y^2\).

Click on an existing comment to edit it further. It will be removed entirely if you clear its content.

Click on the time to change the start or end time.

Accidentally closed the window? No problem. Just go back to the same page and you should be able to restore all your comments and time settings by clicking the Restore button. ×
