Additional Comments
Expander triangle

Use the middle keyword in an object reference or chunk expression.

Comments:

The middle keyword can be used to specify any object. It can also be used in a chunk expression to designate the middle chunk of the specified type.

If the set has an odd number of members, the middle keyword specifies the member halfway between beginning and end. For example,

the middle char of "abc"

is b.

If the set has an even number of members, the middle keyword specifies the first member of the last half of the set. For example,

the middle char of "abcd"

is c.

The word the is optional when using the middle keyword.

A reference to the middle of a string, with no chunk type specified, yields the entire string.
