The following table lists the basic cursor movement commands in Info.
Each entry consists of the key sequence you should type to execute the
cursor movement, the M-x(2) command name (displayed in parentheses), and a short
description of what the command does. All of the cursor motion commands
can take an numeric argument (see section Miscellaneous Commands), to find out how to supply them. With a
numeric argument, the motion commands are simply executed that
many times; for example, a numeric argument of 4 given to
next-line causes the cursor to move down 4 lines. With a
negative numeric argument, the motion is reversed; an argument of -4
given to the next-line command would cause the cursor to move
up 4 lines.
C-n (next-line)
C-p (prev-line)
C-a (beginning-of-line)
C-e (end-of-line)
C-f (forward-char)
C-b (backward-char)
M-f (forward-word)
M-b (backward-word)
M-< (beginning-of-node)
b
M-> (end-of-node)
M-r (move-to-window-line)
M-r moves the cursor to the start of the line in the
center of the window. With a numeric argument of n, M-r
moves the cursor to the start of the nth line in the window.
