Insert Multiple Columns
By clicking on the Insert Multiple Columns, you can insert one or more columns in front of the current column in the Design Matrix. You will be asked how many columns you want to insert. The new columns will be all zeros, which you can then edit.
For example, if your cursor is on the underlined cell, you might chose to insert 2 columns.
