I'm a new user of org-mode and thoroughly enjoying and seeing the benefits it can bring. However, I often want to update my agenda file (it's satisfying). This will read like a 1st world problem, but the only way I've found of refreshing it is by going forward and then backwards in time. Is there a simpler way that I'm missing?
Have you tried typing "r" (no quotes) in agenda mode? See here for the options you have http://orgmode.org/manual/Agenda-commands.html The orgmode manual is big, but you can search within it by adding site:orgmode.org in your online search.
