+@cindex buffer position
A @dfn{position} is the index of a character in the text of a buffer.
More precisely, a position identifies the place between two characters
@deffn Command goto-char position
This function sets point in the current buffer to the value
-@var{position}. If @var{position} is less than 1, it moves point to the
-beginning of the buffer. If @var{position} is greater than the length
-of the buffer, it moves point to the end.

If narrowing is in effect, @var{position} still counts from the
beginning of the buffer, but point cannot go outside the accessible
@deffn Command forward-word &optional count
This function moves point forward @var{count} words (or backward if

``Moving one word'' means moving until point crosses a
