It seems that in Lion, standard shortcuts were added for the Go menu items Back and Forward. The shortcuts (⌘+[ and ⌘+]) are unusable on Finnish keyboard, and I'd like to rebind them. By unusable I mean that e.g. [ is produced with Alt+8 on a Finnish keyboard, and pressing ⌘+Alt+8 does not do anything in Preview.
I have added Forward and Back shortcuts for Preview.app under System Preferences, Keyboard, Keyboard Shortcuts, Application Shortcuts, but Preview only shows the default shortcuts. In Snow Leopard I was able to (re?)bind the actions this way, but it seems that this doesn't work in Lion.
What to do? Navigating huge PDF files without back/forward is painful.

If the System Preferences way of doing that doesn't work, the only other way I can think of remapping the command would be to use something such as Keyboard Maestro or TextExpander. Barring that, though (as they're both paid, third-party apps), there are still two ways to do navigate pages easily:
Trackpad gestures
This only works with multi-touch trackpads, such as the Apple-sold Bluetooth ones or the built-in-to-MacBook ones. Go to
System Preferences > Trackpad > More Gestures
and tick the "Swipe between pages" option. Set it to taste, and use that setting in Preview to switch pages.Page up/down keys
If you have a full-size keyboard, you have page up/page down keys. If not, something that will probably work is using Fn + ↑/↓. This will scroll down and up by approximately one screen's worth. (Tip: Fn + left/right arrows act as Home/End keys.) If all else fails, space and shift-space do the same thing.
