I use Shift+(PgUp/PgDown) while scrolling in the terminal. But it seems to scroll one screen (or a half may be) at a time. I feel comfortable scrolling the terminal by line with the mouse, but don't like to touch it every time. After googling I found Ctrl+Shift+(Up/Down) does this on other Linux systems. But it doesn't seem to work on my CentOS.
Could somebody give the easiest solution to this problem?
