Hello Zendesk team,

I agree the text editor on Zendesk Guide has the flexibility for writing content. 

But it doesn't have "Divider" feature. I think The divider is a useful feature for managing our content. I know we can insert the divider <hr> on the code view. But this way is an indirect approach and time-consuming.

So if Zendesk could update the feature as well as shortcut key, I would appreciate it. 

Please look at the example below(Refer to Jira).
