Is there an example with "more text than fits in a specific rect", to show off scrolling?

[Pomax]

I didn't see anything obvious in the function list or examples that suggests this supports scrollable regions, e.g. if I have a a sidebar and main section, and either has more content than fits on the screen, the user should be able to tab to the section they need and then scroll up/down within that section.

Is that supported? If so, is there an example I missed that shows that off? (And if not, could one be added?)
