Changing Keyboard Functions - IBM 3164 ASCII Manual

Chapter 4. Operations
Changing keyboard functions
4-18
This section tells you how to change the function of some keys by using the
Change Keys key. These keys have an upper-shift a lower-shift and a
control-shift function which may be changed with any shift function of
another key. In the initial default state before you start changing the
functions, the keys with only one engraving on the top have the same
upper-shift and lower-shift function and a control-shift function. An
exception is the PF keys which have a different upper-shift (for example,
PF13) and lower-shift (for example, PF1) function, and an empty control-shift
function which may be defined later. The line drawing keys on the numeric
keypad cannot be redefined.
You can also change the function of these keys from the host system using
the Keyboard Layout Change commands. For more information on these
commands, refer to "Commands and responses" in Chapter 5. This
function enables you to:
• Swap the function of two keys
• Copy a function from one key to another
• Delete a function from the keyboard
• Set a default function
• Check the key IDs.
Shown below are the keys (unshaded) that can be redefined. To redefine a
key, you must enter its I D and shift condition.
The shift conditions are:
• U. upper-shift state
• L: lower-shift state
• C: control-shift state
After you have changed their functions, go to the end of this section to find
out how to change their keycaps. In most cases you will be changing the
three shift functions of a key altogether which will require you to use the key
cap labels for writing in the new names and also the transparent key caps.
Make a copy of the Keyboard Layout Sheet in Appendix C so that you can
write down the location of the keys you changed.
Read through the examples on the following pages to get a better idea of the
keyboard modifying process.
