Thanks to all who answered, but this is not what I was asking for.
I want to add a column or a row by editing the MATRIXFORM output
directly. Not by using a command such as Join.
As I said, I cut/paste the output of MatrixForm to a new cell, now
I need to use the mouse and edit that output to insert a row or
a column right into the MatrixForm representation of the matrix.
