This command presents a dialog that allows the number of columns to be deleted to be specified. The columns will be deleted from every line that is selected, or if no selection is made they will be deleted from the file from every row starting at the current cursor position and proceeding to the last row of the file. If a value of zero '0' is entered, columns will be deleted based on the highlighted text when this command is invoked. This command does not save the deleted text in the clipboard.
