These functions move point based on a count of characters.
goto-char is the fundamental primitive; the other functions use that.
command goto-char position
This function sets point in the current buffer to the value
If narrowing is in effect,
position still counts from the beginning of the buffer, but point cannot go outside the accessible portion. If
position is out of range,
goto-char moves point to the beginning or the end of the accessible portion.
When this function is called interactively,
position is the numeric prefix argument, if provided; otherwise it is read from the minibuffer.
command forward-char \&optional count
This function moves point
count characters forward, towards the end of the buffer (or backward, towards the beginning of the buffer, if
count is negative). If
nil, the default is 1.
If this attempts to move past the beginning or end of the buffer (or the limits of the accessible portion, when narrowing is in effect), it signals an error with error symbol
In an interactive call,
count is the numeric prefix argument.
command backward-char \&optional count
This is just like
forward-char except that it moves in the opposite direction.
