Controls whether indentation commands such as Indent and Indent Form insert whitespace using #\Space or #\Tab characters when changing the indentation of a line.
The initial value is
nil
, meaning that only the #\Space character is inserted.
A true value for editor:*indent-with-tabs* causes the indentation commands to insert #\Tab characters according to the value of Spaces-For-Tab and then pad with #\Space characters as needed.
