30.2.1 Motion by Characters
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 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.
