Select a page in the page tree and wait for the module to show it. Name the page by its title, or by its path from a page that is already shown ("Content Examples > Text > Rich Text"): every page on the path is expanded on the way. The title is matched as a whole.
Examples
When I select the "Congratulations" page in the page tree
When I select the "Congratulations > Features" page in the page tree
When we select the "Congratulations > Content Examples > Text > Rich Text" page in the page tree
And I select the "Features" page in the page tree
When select the "Congratulations > Pages" page in the page tree
Pattern
When(/^(I |we )*select the "([^"]*)?" page in the page tree$/, …)
