No I'm talking about scrolling in the actual program running - it's most useful in a pager obviously, but it also works for editors, and it works both locally (OS X, built-in Terminal.app) and over SSH on Debian hosts.

I'll be honest - I have ~no idea~ (edit: apparently there are xterm control sequences for mouse scrolling) how it's actually implemented, but several tools have some reference to mouse support (tmux, vim, etc) in option/config files, so it's probably available for your distro/platform and just needs to be enabled.

Further edit: (or PS. or whatever):

`less` pager supports mouse scrolling. `more` pager does not!
