+@subsection Clocking work time
+
+Org-mode allows you to clock the time you spent on specific tasks in a
+project.  When you start working on an item, you can start the clock.
+When you stop working on that tast, or when you makr the task done, the
+clock is stoppend and the corresponding time interval is recorded.  It
+also computes the total time spent on each subtree of a project.
+
+@table @kbd
+@kindex C-c C-x C-i
+@item C-c C-x C-i
+Start the clock on the current item (clock-in).  This inserts the CLOCK
+keyword together with a timestamp.
+@kindex C-c C-x C-o
+@item C-c C-x C-o
+Stop the clock (clock-out).  The inserts another timestamp at the same
+location where the clock was last started.  It also directly computes
+the resulting time in inserts it after the time range as @samp{=>
+HH:MM}.
+@kindex C-c C-t
+@item C-c C-t
+Changing the TODO state of an item to DONE automatically stops the clock
+if it is running in this same item.
+@kindex C-c C-x C-x
+@item C-c C-x C-x
+Cancel the current clock.  This is useful if a clock was started by
+mistake, or if you ended up working on something else.
+@kindex C-c C-x C-d
+@item C-c C-x C-d
+Display time summaries for each subtree in the current buffer.  This
+puts overlays at the end of each headline, showing the total time
+recorded under that heading, including the time of any subheadings. You
+can use visibility cycling to study the tree, but the overlays disappear
+automatically when the buffer is changed.

+The @kbd{l} key may be used in the timeline (@pxref{Timeline}) and in
