Yes if this video shows anything it's that you need a real GUI. The curse one is ok, but what's the point if nobody knows it exists and you need obscure commands just to scroll?
You scroll with the arrow keys. The "obscure commands" (ctrl-p and ctrl-n) are to get to the Previous and Next commands typed and are more or less universal in unix command line systems.
I've used Unix a lot and I've never used Ctrl-P or Ctrl-N for previous/next. Ask 99% of people what those do and they'll either have no idea or say Print, New. Ask 99.999999% of people how you scroll in gdb and none of them will guess Ctrl-P/Ctrl-N. It's shit.
