The documentation for analogReference is misleading

[nickgammon]

The page for analogReference ( http://arduino.cc/en/Reference/AnalogReference ) has the word (type) in the heading, like this:

analogReference(type)

That implies that analogReference is a type, rather than a function. Also there is no example of calling it, adding to the confusion.

I suggest removing "(type)" from the heading, and adding an example, eg.

analogReference (INTERNAL);   // use the internal reference voltage
analogReference (DEFAULT);    // use the default reference voltage

[matthijskooijman]

I suspect that the (type) is intended to mean that the function takes a single argument, called "type". However, that notation is inconsistent with other functions, which have just the function name in the heading and have a "syntax" section that shows the arguments to the function. Making this consistent sounds like a good plan.
