Multiple columns
================

   When using several lines in an expression, see  Multiple lines, it is
often necessary to align parts of lines under each other, for instance
having several lines with a "=" in the middle. It is also possible to
make very simple tables - this might be expanded heavily in an later
version, see  Future.

   Using multiple columns is very simple, just press tab and you will
get a new column, which is seperated a little from the prior. When
making a new line and pressing tab there, the cursor will be positioned
under the beginning of the next column, which means that currently the
columns are leftjustified.
