How to scroll the terminal emulator window in smaller steps using the keyboard?

Question

How could I scroll up and down the bash shell window (without the mouse or scroll bars, just using the keyboard)?

Shift+PageUp and Shift+PageDown acts like page up and page down.

But how could one scroll just one line up or down? Shift+Up and Shift+Down doesn't work.

Answer 1

Gnome terminal (and others) uses ctrl+shift+up and ctrl+shift+down to scroll one row.
But ctrl+shift should work in most other terminal emulators (like xterm or urxvt if not intercepted by windows managers or stuff.
