How can I decrease (or generally change) the mouse wheel scroll amount in Ubuntu? I didn't mean the speed of scroll, and the thing I want is just the amount. for example, when reading a document, I want to scroll one line instead of three lines (with scrolling a little).

12.04 has smooth scrolling so for instance you can scroll in gedit 1 line at a time. –  doug Mar 24 '12 at 18:02
It seems to be a bug: bugs.launchpad.net/gtk/+bug/124440 –  Takkat Mar 24 '12 at 18:35
No, no, that's not a bug, I just want it to be a little bit different. If 12.04 has smooth scrolling, that will be OK. –  Keyhan Asghari Mar 24 '12 at 19:20
