Pause in ansible playbook waiting for user intervention

How to use sleep in playbook ?

---
- hosts: webservers
  tasks:
  - name: install tftp
    yum: pkg=tftp state=installed
    failed_when: False
  - pause: minutes=5


--
- pause: minutes=5

--

It shows the option
Pausing for 300 seconds
(ctrl+C then 'C' = continue early, ctrl+C then 'A' = abort)

So, C to continue early and A to abort.

This can be used for ansible debugging.
We can exit a playbook after a (debugging) role.
