If the columns actually align and one wants to make changes on every line, this is a good suggestion. However, in the example the OP gave, that 3rd line didn't line up vertically with the first two lines, making it a bit more difficult to use visual-block insert. :( It also sounded like the OP may not want to insert "xx_" on _every_ line, but perhaps rather selectively. -tim
