+******************
+Writing Statistics
+******************
+
+When you work on a project, a log file records when you opened it, when you closed it, and the
+total word counts of your novel documents and notes at the end of the session, provided that the
+session lasted either more than 5 minutes, or that the total word count changed. For more details
+about the log file, see :ref:`docs_technical_storage`.
+
+A tool to view the content of the log file is available in the **Tools** menu under **Writing
+Statistics**. You can also launch it by pressing :kbd:`F6`, or find it on the sidebar.
+
+The tool will show a list of all your sessions, and a set of filters to apply to the data. You can
+also export the filtered data to a JSON file or to a CSV file that can be opened by a spreadsheet
+application like for instance Libre Office Calc or Excel.
+
+.. versionadded:: 1.2
+
+   As of version 1.2, the log file also stores how much of the session time was spent idle. The
+   definition of idle here is that the novelWriter main window loses focus, or the user hasn't made
+   any changes to the currently open document in five minutes. The number of minutes can be altered
+   in **Preferences**.
+
+
+Session Timer
+=============
+
+A session timer is by default visible in the status bar. The icon will show you a clock icon when
+you are active, and a pause icon when you are considered "idle" per the criteria mentioned above.
+
+If you do not wish to see the timer, you can click on it once to hide it. The icon will still be
+visible. Click the icon once more to display the timer again.
+
+.. versionadded:: 2.6
+
+   As of version 2.6, clicking the timer text or icon in the status bar will toggle its visibility.
