8.4.1 Clocking commands
- C-c C-x C-i (
Start the clock on the current item (clock-in). This inserts the CLOCK
keyword together with a timestamp. If this is not the first clocking of
this item, the multiple CLOCK lines will be wrapped into a
:LOGBOOK: drawer (see also the variable
org-clock-into-drawer). You can also overrule
the setting of this variable for a subtree by setting a
When called with a C-u prefix argument,
select the task from a list of recently clocked tasks. With two C-u
C-u prefixes, clock into the task at point and mark it as the default task;
the default task will then always be available with letter d when
selecting a clocking task. With three C-u C-u C-u prefixes, force
continuous clocking by starting the clock when the last clock stopped.
While the clock is running, the current clocking time is shown in the mode
line, along with the title of the task. The clock time shown will be all
time ever clocked for this task and its children. If the task has an effort
estimate (see Effort estimates), the mode line displays the current
clocking time against it1 If the task
is a repeating one (see Repeated tasks), only the time since the last
reset of the task 2
will be shown. More control over what time is shown can be exercised with
CLOCK_MODELINE_TOTAL property. It may have the values
current to show only the current clocking instance,
show all time clocked on this task today (see also the variable
all to include all time, or
auto which is the default3.
Clicking with mouse-1 onto the
mode line entry will pop up a menu with clocking options.
- C-c C-x C-o (
Stop the clock (clock-out). This inserts another timestamp at the same
location where the clock was last started. It also directly computes
the resulting time and inserts it after the time range as ‘=>
HH:MM’. See the variable
org-log-note-clock-out for the
possibility to record an additional note together with the clock-out
- C-c C-x C-x (
Reclock the last clocked task. With one C-u prefix argument,
select the task from the clock history. With two C-u prefixes,
force continuous clocking by starting the clock when the last clock
- C-c C-x C-e (
Update the effort estimate for the current clock task.
- C-c C-c or C-c C-y (
Recompute the time interval after changing one of the timestamps. This
is only necessary if you edit the timestamps directly. If you change
them with S-<cursor> keys, the update is automatic.
- C-S-<up/down> (
CLOCK log lines, increase/decrease both timestamps so that the
clock duration keeps the same.
- S-M-<up/down> (
CLOCK log lines, increase/decrease the timestamp at point and
the one of the previous (or the next clock) timestamp by the same duration.
For example, if you hit S-M-<up> to increase a clocked-out timestamp
by five minutes, then the clocked-in timestamp of the next clock will be
increased by five minutes.
- 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.
- C-c C-x C-q (
Cancel the current clock. This is useful if a clock was started by
mistake, or if you ended up working on something else.
- C-c C-x C-j (
Jump to the headline of the currently clocked in task. With a C-u
prefix arg, select the target task from a list of recently clocked tasks.
- 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 when you change the
buffer (see variable
org-remove-highlights-with-change) or press
The l key may be used in the timeline (see Timeline) and in
the agenda (see Weekly/daily agenda) to show which tasks have been
worked on or closed during a day.
Important: note that both
org-clock-in-last can have a global keybinding and will not
modify the window disposition.
