Keybinding to jump to next file

[notramo]

It currently requires too muck keystrokes. Also, jumping to previous file should also be possible.

To jump to any file that was specified on the most command line, press the ":" key then press "n". This will cause the name of the next file on the list to appear at the bottom of the screen. To scroll through previous (next) files from the list, press the Down (Up) arrow key one or more times.

But I want to be able to quickly switch between files with one single keystroke. E.g. I press F3, then it jumps to next file, I read something, then I press F2 to jump back to previous.
