Changing the Location of Point
To do more than insert characters, you have to know how to move
point (Note: Point.). The simplest way to do this is with arrow keys
or the left mouse button.
There are also control and meta characters for cursor motion. Some
are equivalent to the arrow keys (these date back to the days before
terminals had arrow keys, and are usable on terminals which don't have
them). Others do more sophisticated things.
Move to the beginning of the line (`beginning-of-line').
Move to the end of the line (`end-of-line').
Move forward one character (`forward-char').
Move backward one character (`backward-char').
Move forward one word (`forward-word').
Move backward one word (`backward-word').
Move down one line, vertically (`next-line'). This command
attempts to keep the horizontal position unchanged, so if you
start in the middle of one line, you end in the middle of the
next. When on the last line of text, `C-n' creates a new line and
moves onto it.
Move up one line, vertically (`previous-line').
Move point to left margin, vertically centered in the window
(`move-to-window-line'). Text does not move on the screen. A
numeric argument says how many screen lines down from the top of
the window (zero for the top line). A negative argument counts
lines from the bottom (-1 for the bottom line).
Move to the top of the buffer (`beginning-of-buffer'). With
numeric argument N, move to N/10 of the way from the top. *Note
Arguments::, for more information on numeric arguments.
Move to the end of the buffer (`end-of-buffer').
Read a number N and move cursor to character number N. Position 1
is the beginning of the buffer.
Read a number N and move cursor to line number N. Line 1 is the
beginning of the buffer.
Use the current column of point as the "semipermanent goal column"
for `C-n' and `C-p' (`set-goal-column'). Henceforth, those
commands always move to this column in each line moved into, or as
close as possible given the contents of the line. This goal
column remains in effect until canceled.
`C-u C-x C-n'
Cancel the goal column. Henceforth, `C-n' and `C-p' once again
try to avoid changing the horizontal position, as usual.
If you set the variable `track-eol' to a non-`nil' value, then `C-n'
and `C-p' when at the end of the starting line move to the end of
another line. Normally, `track-eol' is `nil'. Note: Variables, for
how to set variables such as `track-eol'.
Normally, `C-n' on the last line of a buffer appends a newline to
it. If the variable `next-line-add-newlines' is `nil', then `C-n' gets
an error instead (like `C-p' on the first line).
