A few keyboard shortcuts aren't working as I'd expect in OSX Mavericks (10.9.5) on a 2011 Macbook Pro using a US keyboard layout.

• command-F triggers search instead of toggling fullscreen (alt-enter works, so that's okay)
• cmd+arrows don't perform the normal navigation functions (home, end, pgup, pgdn)
• ctrl+up/down triggers pgup/down (not expected, but nice to know)

If anyone has suggestions for alternatives that would be great.
