If I have three windows open in Safari and minimize one of them, then I try to switch between windows by pressing Control+' it only switches to windows that re not minimized. How do I include that window that was minimized?
I don't know any keyboard shortcut, but it's doable with mouse/trackpad with exposé in both Lion and Snow Leopard.
In Lion there is a 4 finger down gesture to get all current app windows. In Snow Leopard, clicking and holding an icon in the dock for 2 seconds does this too, it can be bound to a screen edge (hot corner) or a mouse button.
