Keyboard Mapping
Overview
Introduction
Some of the keys on a 3270 terminal are not present
on most computer
and workstation keyboards. When a key or key combination is pressed on
your keyboard JET 3270 can emulate the effect of a different
key from a 3270 terminal being pressed. JET 3270 is said to
"map" the keyboard key to the 3270 terminal key. JET
3270 can also run a script when a key or key combination is
pressed. In this case JET 3270 maps the keyboard key to the
script. The set of all maps
from keyboard keys to 3270 terminal keys or scripts is
called a "keyboard
mapping". JET 3270 allows the user to configure its keyboard
mapping via the session settings.
As a Java applet JET does not access the keyboard
directly. When you press a key the browser will interpret the key and
usually pass it to JET. However, sometimes the
operating system or browser interprets the key as having meaning to
itself or as illegal and does not pass it to JET. For
example, when running JET in Microsoft Internet Explorer
under Windows 95, Alt+F6 is interpreted by Windows 95 as a
request to switch windows and is not passed to
JET.
The default keyboard mapping is shown in the table below. Note that
several key combinations can map to the same 3270 key.
The table has a row
for each 3270 key which lists the key combinations which
map to that 3270 key.

JET 3270 will also map from a key combination that generates
a graphic character (for example, letters, digits, punctuation and
the space) to the 3270 key for that graphic character.
Netscape Communicator
and Windows 95
Some of the details of what key combinations Netscape Communicator
4.73 running under Windows 95 passes to JET 3270 are
described below.
Print Screen is not passed.
Ctrl+Esc and Ctrl+Shift+Esc bring up the Windows 95 Start menu and are
not passed.
The left Windows key is passed as the left square bracket key.
The right Windows key is passed as the back slash key.
They are also interpretted by Window 95, causing the Start menu
to be displayed. The Menu key is passed as the right square bracket
key.
When Num Lock is off the 5 on the numeric key pad is passed as
the Clear key.
Alt+F4 closes the session.
Alt+F6 is caught by Windows 95 and switches between
multiple windows in the same program, it is not
passed to JET 3270.
Alt+Tab is caught by Windows 95 and switches to the window
you last used, it is not passed to JET 3270.
Alt+Esc is caught by Windows 95 and puts the current window
at the back, it is not passed to JET 3270.
Microsoft Internet Explorer 5.01 and Windows 95
Some of the details of what Input Events Microsoft Internet Explorer
5.01 with Microsoft Virtual Machine 3234
running under Windows 95 passes to JET 3270 are described below.
Print Screen is not passed.
The left Windows key is passed as the left square bracket key.
The right Windows key is passed as the back slash key.
They are also interpretted by Window 95, causing the Start menu
to be displayed. The Menu key is passed as the right square bracket
key.
When Num Lock is off the 5 on the numeric key pad is passed as
the Clear key.
Ctrl+Esc and Ctrl+Shift+Esc bring up the Windows 95 Start menu and are
not passed.
Alt+space pops up the window menu and is passed.
Alt+F4 closes the session.
Alt+F6 is caught by Windows 95 and switches between multiple windows
in the same program, it is not passed.
Alt+Tab is caught by Windows 95 and switches to the window you last
used, it is not passed.
Alt+Esc is caught by Windows 95 and puts the current window
at the back, it is not passed.
Netscape Communicator and Solaris
Some of the details of what key combinations Netscape Communicator
running under Solaris passes to JET 3270 are described below.
Under Solaris, Communicator receives keyboard
input via the X window
system. Communicator uses the window system's keymap table
to translate the event keycodes it receives
from the window system to keysyms. The xmodmap command is used
to view and change the keymap table. The following assumes the default
keymap table.
F6 and F7 are caught by the window system, they are not passed
to JET 3270.
F11 and F12 are not passed. This is because the default keymap
table translates the F11 and F12 keycodes to SunF36 and SunF37
respectively.
The Alt key does not function as an Alt modifier key.
The Meta key (marked with a diamond) functions as combined
Alt and Meta modifier keys. For example, if the Meta key is held
and the A key pressed JET 3270 receives Alt+Meta+A. The
ignore_meta_for_unix applet parameter can
make JET 3270 ignore the received Meta key, so that the Meta
key functions as an Alt modifier key. For example, if
ignore_meta_for_unix is set to
yes, the Meta key is held and the
A key pressed JET 3270 receives Alt+A. The default value
for ignore_meta_for_unix is
yes.
