In org-mode, how to cancel task scheduling?

Question

This seems trivial, but if you attempt to schedule a task and change your mind, how do you just cancel without actually setting a task.

C-j exits, but sets the date (like return)

C-k kills the active buffer, but doesn't work

Answer 1

From the org mode info pages, section 8.3.1 Inserting deadlines or schedules:

`C-c C-s     (`org-schedule')'
     Insert `SCHEDULED' keyword along with a stamp.  Any CLOSED
     timestamp will be removed.  When called with a prefix argument,
     remove the scheduling date from the entry.

So you can abort the input C-g and call the scheduling with a prefix argument C-u C-c C-s to remove the date/time.
