I would like to assing the function org-timer-start with a univerals argument to its own key.
I read here, that one should look into the source code of a function to find out how to pass a universal argument.
Where is this part in the following function, that tells me about the universal argument call?
(defun org-timer-start (&optional offset)
"Set the starting time for the relative timer to now.
When called with prefix argument OFFSET, prompt the user for an offset time,
with the default taken from a timer stamp at point, if any.
If OFFSET is a string or an integer, it is directly taken to be the offset
without user interaction.
When called with a double prefix arg, all timer strings in the active
region will be shifted by a specific amount. You will be prompted for
the amount, with the default to make the first timer string in
the region 0:00:00."
(interactive "P")
(cond
((equal offset '(16))
(call-interactively 'org-timer-change-times-in-region))
(org-timer-countdown-timer
(user-error "Countdown timer is running. Cancel first"))
(t
(let (delta def s)
(if (not offset)
(setq org-timer-start-time (current-time))
(cond
((integerp offset) (setq delta offset))
((stringp offset) (setq delta (org-timer-hms-to-secs offset)))
(t
(setq def (if (org-in-regexp org-timer-re)
(match-string 0)
"0:00:00")
s (read-string
(format "Restart timer with offset [%s]: " def)))
(unless (string-match "\\S-" s) (setq s def))
(setq delta (org-timer-hms-to-secs (org-timer-fix-incomplete s)))))
(setq org-timer-start-time (org-time-since delta)))
(setq org-timer-pause-time nil)
(org-timer-set-mode-line 'on)
(message "Timer start time set to %s, current value is %s"
(format-time-string "%T" org-timer-start-time)
(org-timer-secs-to-hms (or delta 0)))
(run-hooks 'org-timer-start-hook)))))
Do I need to make a custom fuction to call org-timer-start with a Ctrl-u prefix?
