{\bf Correction:}

The Scheme function {\tt PRINT-GRAPHICS-FILE}, which is the last entry in the
{\bf Scheme Reference} chapter, is now called {\tt PRINT-PICTURE-FILE}.  It
works exactly as described under the old name.

{\bf Note:}

If you are running a Scheme program and wish to stop it, press \key{abort};
this will immediately stop the program and return control to you (i.e., all
Edwin commands will work again).  Likewise, if you want to stop whatever
operation Edwin is performing, or to cancel an Edwin command you've already
begun typing, use the \key{abort} key.
