I'm not aware of the details of your OS and browser so I can't comment
on specific key combinations.

Specifically I don't know if Ctrl-F5 is any different to Ctrl-R in your
environment, but a simple Ctrl-R reload has never done anything other
than reload, using whatever cached results are available. In most cases
that won't go to the server at all it will just reuse the tiles the
browser already has.

A forced reload (typically Ctrl-Shift-R) is what forces the browser to
check with the server, and to request that any caches in the path try
to revalidate with their upstream.
