— Command: goto-char position

This function sets point in the current buffer to the value position.

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.

goto-char returns position.

— 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 count is 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 beginning-of-buffer or end-of-buffer.

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.
