Use ⌘~ to switch between windows of an application
On a mac, you can use Cmd-tilde (⌘~) to switch between the different open windows of an application.
The tilde is conveniently placed right above the Tab key (⇥). So this combination is very similar to the one used to sitch between apps (Cmd-Tab ⌘⇥).
I just found out about this. Woohoo!
(On the german keyboard layout, the default combination is ‘⌘<’, which is not as conveniently placed as on the english layout. You can change this in System Preferences -> Keyboard and Mouse. I changed it to ‘⌘^’ which is the equivalent of the english combination.)
