[Keyboard Shortcuts]
• The list of available shortcuts is missing the ⌘+↑ and ⌘+↓ shortcuts for jumping between files
• It would be great to have a shortcut for marking the currently focused file as viewed
• The next/previous shortcuts wrap around from top -> bottom and bottom -> top which is a little disorienting. I think it would be great if there was some amount of friction point there (like hit twice quickly to go around or maybe jump to top/bottom)
