[Orgmode] command f in agenda buffer

[Curiouslearn]

Hi all,

When I press C-c a a, I end up with the agenda view for the current
week. I want to then view the agenda for the next week and I press key
f. I read that I have to press this key to
"Go forward in time to display the following org-agenda-ndays days.
For example, if the display covers a week, switch to the following
week. With prefix arg, go forward that many times org-agenda-ndays
days. "

However, when I press f, my emacs toggles between follow mode on and
off. How do I go the next week in the agenda view?

Thanks for your help.
