I have just been given this advice on a Google Docs help site

Google Docs should update automatically, but depending on your browser
settings you may not experience such a change right away (and it even
may lead to errors).
In essence have your browser check web pages for updates every time a
web page is accessed. This makes sure Google Docs updates are always
directly available.

Can Chrome be set to always check for updates on webpages in this way?
(The 'problem' I have is not knowing how to update Google Docs or how to make sure that I automatically get updates. Just as irritating is the fact that there is no notification of updates, so a new formatting feature may not be discovered for a while. But that is another question.)
