PEN(9.6)                                                              PEN(9.6)

NAME
       pen - doodle anywhere on the screen

SYNOPSIS
       pen

DESCRIPTION
       Pen  writes on the screen with smooth strokes.  It can scribble on lay‐
       ers or on the background, even while other programs  are  running.   It
       can be used to make drawings, marks or annotations, or to highlight re‐
       gions in a crowded screen.  Pen never needs refilling.

       To  write,  press  mouse  button 1 and keep it pressed while moving the
       mouse.  To move around without writing, release the button.   Button  3
       controls  a menu to stop drawing (allowing one to resume normal activi‐
       ties), resume drawing, clean up, or exit the program.

BUGS
       When drawing too fast, the pen can temporarily run  out  of  ink;  when
       this  happens release button 1 and press it again.  To avoid this prob‐
       lem, make the pen layer bigger (that is where the ink supply is kept).
