Selector Pen
Overview
JET 3270 emulates a 3270 terminal's selector pen (also
called a light pen) using the mouse. You can configure JET 3270
so that clicking on the terminal screen has a similar effect to
pressing the tip of the selector pen to the screen on a real
3270 terminal.
When you click one of the mouse buttons configured to emulate a
selector pen the cursor moves to the location clicked and selects it
(if the field is selector pen detectable). Moving the cursor to
the location and pressing the keys for Cursor Select (Alt+F9 by
default) has the same effect.
As a Java applet JET does not access the mouse directly and does
not know how many buttons your mouse has. Java supports a three
button mouse. On platforms that support fewer than three mouse
buttons modifier keys can be used to simulate extra mouse
buttons. For example, button 2 can be simulated by holding the Alt
key and clicking. The following table shows how to generate the
three buttons in various environments.
