How to remove/delete attachment; and add desription to attachment?

I am following the instructions at page https://zohowikihelp.wiki.zoho.com/Attachments.html.

The Instructions to remove and delete an attachment refer to a remove link and a delete link. However, I can find neither in the actual dialog, and on that doc page there's no indication of such links. Where are they?

Also, I see that floating the mouse over an existing attachment description causes an edit icon to appear. Is there a corresponding way to add a description to an attachment that doesn't have one?

Thanks!
