After the window is created, it is usually switched to a private buffer using C-X B or (perhaps more often) C-X C-V. Note that because both windows are displaying the same buffer, reading a file in one window with C-X C-R probably does not do what you want. [C-X 1] This is the basic window destroying command. All windows but the current window are removed from the screen. The current window grows to fill the vacated screen space. Any argument is ignored. [C-X N] Move to the next window down the screen. If the current window is the bottom window, move to the top window. Ignores any argument. [C-X P] Move to the previous window up the screen. If the current window is the top window, move to the bottom window. Ignores any argument. [C-X Z] The current window is enlarged, if possible. Any argument is used as a ``number of lines by which to grow''. The default argument is 1. Screen space is stolen from the window immediately below the current window. If the current window is the bottom window on the screen then space is stolen from the window immediately above the current window. You cannot steal all of the lines away from a window. [C-X C-N] Scroll the current window down. Any argument is used as a ``number of lines by which to scroll'' count. The default argument is 1. [C-X C-P] Scroll the current window up. Any argument is used as a ``number of lines by which to scroll'' count. The default argument is 1. [C-X C-Z] The current window is shrunk, if possible. Any argument is used as a ``number of lines by which to shrink''. The default argument is 1. Screen space is given to the window immediately below the current window. If the current window is the bottom window on the screen, the space is given to the window immediately above the current window. You cannot shrink a window out of existance. [M-!] This command is used to control the line of a window upon which dot is displayed. If its argument is positive, then that number is taken to be the origin 1 line number of the current window upon which the line containing dot should be placed. If its argument is 0, then dot is moved to the center of the window. If the number is less then zero then it is taken to be the negation of the origin 1 line number of the current window starting at the bottom upon which the line containing dot should be placed. If no argument is supplied, a default argument of 1 is used; This lets M-! function as a ``move dot to the top of the window'' command, which is very useful.
