 ==============================================================================
+&NUMBER FORMATS&
+
+    Numbers follow cell-specific format if set by the :format command.
+    Otherwise they default to column specific format, which can be set by the
+    scripting command FORMAT. The scripting FORMAT command has the syntax
+        FORMAT {COLUMN} {WIDTH} {PRECISION} {TYPE}
+        where TYPE is one of:
+            0   Fixed-point
+            1   Scientific format
+            2   Engineering format
+    The default column format is (10 2 0), meaning width 10, precision 2, and
+    fixed-point. The column format width follows changes to the column width.
+
+    Note: If the exponent is too large (>10^21) or too small (<10^-18), the
+    scientific format is used.

+&Entering Greek and Math operator symbols&
+
+    Greek letters and a large set of math symbols available in UTF-8
+    can be entered and will display, provided your terminal supports them.
+
+    The full list is given below. In each column, left of the equal sign is
+    the keyboard sequence to be entered, to obtain the character on the right
+    of the equal sign.
