Left
Set Left [n]
(Default: first column)
Set Left specifies a temporary left margin for your file. Existing data to the left of the margin is not changed (unless you delete a line). When you copy or move a line with Add, the entire line is moved. If you add new lines, they will contain spaces to the left of the margin.
Set Left applies to all Qedit commands, including Visual, Modify, List, and Keep. Don’t forget to reset Set Left when you want to Keep a file.
Set Left resets the Set Window columns for string searches. See also Set Right.
