Promote the content of the form to the lists of promoted content (the home page of a standard site) or keep it out of them, and make it sticky at the top of lists or not: the "Promote" and "Make sticky at top of lists" checkboxes of the publishing options. The two checkboxes share one accessible name ("Additional actions"), so a step that ticks a checkbox by its label does not find them.
Examples
When I set the content to be promoted
When I set the content to be not promoted
And I set the content to be sticky
When we set the content to be not sticky
And set the content to be not promoted
Pattern
When(/^(I |we )*set the content to be (not )?(promoted|sticky)$/, …)
