It is an alias for c("render", "server-start"). The results will appear in a small pop-up window next to the code (Figure \@ref(fig:notebook-inline-output)). If a certain option needs to be frequently set to a value in multiple code chunks, you can consider setting it globally in the first code chunk of your document, e.g..
