All MIDAS display commands will work on these window displays, some have to be implemented in software which makes them slow <I>e.g.</I> <TT>ZOOM</TT> and <TT>SCROLL</TT>. The cursor is implemented through the mouse on which the left button is <B>Enter</B> and the middle button (or right button on a 2 button mouse) is <B>Exit</B>. When the cursor is positioned on a feature it is also possible to use the <B>Return</B> key to read the cursor location. Some commands use a second cursor which is implemented through the arrow key on the keyboard. <P> <BR><HR> <ADDRESS> <I>Petra Nass</I> <BR><I>1999-06-09</I> </ADDRESS> </BODY> </HTML>
