ERASE

The function ERASE clears the entire graphics window. This command is
available in the PLOT menu, as well as in the plotting windows accessible
through the soft menu keys.

MENU

Pressing @MENU will remove the soft key menu labels to show the graphic
unencumbered by those labels. To recover the labels, press L.

SUB

Use this command to extract a subset of a graphics object. The extracted
object is automatically placed in the stack. Select the subset you want to
extract by placing a MARK at a point in the graph, moving the cursor to the
diagonal corner of the rectangle enclosing the graphics subset, and press
@@SUB@. This feature can be used to move parts of a graphics object around the
graph.

REPL

This command places the contents of a graphic object currently in stack level
1 at the cursor location in the graphics window. The upper left corner of the
graphic object being inserted in the graph will be placed at the cursor
position. Thus, if you want a graph from the stack to completely fill the
graphic window, make sure that the cursor is placed at the upper left corner
of the display.

PICT

This command places a copy of the graph currently in the graphics window
on to the stack as a graphic object. The graphic object placed in the stack
can be saved into a variable name for storage or other type of manipulation.

X,Y

This command copies the coordinates of the current cursor position, in user
coordinates, in the stack.
