When I create an appointment in org-agenda I make use of timestamps. The item is created with today's date and time and I then place my cursor on the date and time respectively and use S-up or S-down to increase or decrease the time until I get to the time I need. I see that time increments by default are 5 minutes. I would prefer it to be 30 minutes. Can can I achieve this?

  • Are you sure you are pressing CONTROL- {up, down} to change the times? Might you be pressing SHIFT-{up, down} instead? This does not affect the question and answer, but it might confuse people reading this.

  • Mea Culpa. I meant to say Shift-up and Shift-down. Apologies.

S-up and S-down are bound to org-shiftup and org-shiftdown. On timestamps, these call org-timestamp-up and org-timestamp-down respectively. These methods use the variable org-time-stamp-rounding-minutes:

Number of minutes to round time stamps to.

These are two values, the first applies when first creating a time stamp.

The second applies when changing it with the commands ‘S-up’ and ‘S-down’.

When changing the time stamp, this means that it will change in steps of N minutes, as given by the second value.

So we can change the second value to 30:

(setf (elt org-time-stamp-rounding-minutes 1)
      30)

And now these methods will move by 30 minutes[1].

[1] It will move to the nearest multiple of this value; S-up once on <2019-10-09 Wed 06:27> will move it to <2019-10-09 Wed 06:30>; calling it again gives <2019-10-09 Wed 07:00>.

    When you say C-up and C-down, you really mean S-up and S-down, don't you? See the doc string of the variable that you quoted.

  • @NickD Neither S-up nor S-down is not bound on my version of org, and the OP in the question says they're using C-up and C-down, so I used the Ctrl versions in the answer.

  • What version is that? AFAIK, org-shiftup and org-shiftdown have always been bound to S-up and S-down (hence the function names: these settings are ancient).

  • I should add that these settings are the default on GUI emacs, but even on console emacs, they are supposed to work: see the doc string for org-support-shift-select.

  • On the computer I'm at now, which is running a GUI emacs, I have Org 9.1.9.
