Scrollup
Set Visual Scrollup 'nnn | "char"
(Default="-")
You can enter a minus sign in one (or both) copy/paste columns in full-screen mode. A single character scrolls up the number of lines defined in the |5Set Visual Roll option. Enter 2 minus signs to scroll up twice the number of lines and so on.
The minus sign is the default scrollup character. You can change it to another character that you may find easier to type. It must be a printable character and must not be a valid copy/paste code. Valid codes are: A B C D F G H J M P R V Z ? !. Use Set Visual Scrollup "c" to change the character.
You can enter Set Visual Scrollup "" to reset it back to the default character.
