Shifts the text in this window up to show more of the node which is currently below the bottom of the window. A numeric argument shows that many more lines at the bottom of the window; a numeric argument of 4 shifts all text in the window up 4 lines (discarding the top 4 lines), and shows four new lines at the bottom of the window. Without a numeric argument, Spacebar takes the bottom two lines of the window and places them at the top of the window, redisplaying almost a completely new screenful of lines.

Del /Delete (scroll-backward)
M-v

Shifts the text in this window down, the inverse of scroll-forward. scroll-forward and scroll-backward moves forward and backward through the node structure of the file. If you press Spacebar while viewing the end of a node, or Del while viewing the beginning of a node, what happens is controlled by the variable scroll-behavior. See Manipulating variables for more information.

C-l (redraw-display)

Redraws the display from scratch, or shifts the line whit the cursor to a specified location. With no numeric argument, ‘C-l’ clears the screen, and then redraws its entire contents. With a numeric argument of n, the line with the cursor is shifts to the nth line of the window.

C-x w (toggle-wrap)

Toggles the state of line wrapping in the current window. Normally, when lines wrap when they are longer than the screen width,; i.e., they continue on the next line. Lines which wrap display a ‘\’ in the rightmost column of the screen. You can cause such lines to be terminated at the rightmost column by changing the state of line wrapping in the window with C-x, w. When a line contains more than one screen width, ‘$’ appears in the rightmost column of the line, and the remainder is invisible.
