M-x picture mode
C-c .

,----
| picture-mode is an interactive compiled Lisp function in `picture'.
| (picture-mode)
| 
| Switch to Picture mode, in which a quarter-plane screen model is used.
| Printing characters replace instead of inserting themselves with motion
| afterwards settable by these commands:
|   C-c <         Move left after insertion.
|   C-c >         Move right after insertion.
|   C-c ^         Move up after insertion.
|   C-c .         Move down after insertion.
|   C-c `         Move northwest (nw) after insertion.
|   C-c '         Move northeast (ne) after insertion.
|   C-c /         Move southwest (sw) after insertion.
|   C-c \   Move southeast (se) after insertion.
|   C-u C-c `  Move westnorthwest (wnw) after insertion.
|   C-u C-c '  Move eastnortheast (ene) after insertion.
|   C-u C-c /  Move westsouthwest (wsw) after insertion.
|   C-u C-c \  Move eastsoutheast (ese) after insertion.
| The current direction is displayed in the mode line.  The initial
| direction is right.  Whitespace is inserted and tabs are changed to
| spaces when required by movement.  You can move around in the buffer
| with these commands:
|   M-x picture-move-down         Move vertically to SAME column in previous 
line.
|   M-x picture-move-up   Move vertically to SAME column in next line.
|   M-x picture-end-of-line       Move to column following last non-whitespace 
character.
|   M-x picture-forward-column    Move right inserting spaces if required.
|   M-x picture-backward-column   Move left changing tabs to spaces if required.
|   C-c C-f Move in direction of current picture motion.
|   C-c C-b Move in opposite direction of current picture motion.
|   Return  Move to beginning of next line.
