Using Your Keyboard
Keyboard Maps
This section describes the keyboard maps shown in Appendix C and the function of
the keys on 3270 and non-3270 terminals.
At a 3270 terminal, the keyboard functions are associated with one key on the
keyboard. For example, you press the PFI key for the PFI function. However, the
ASCII terminals that are supported by the 3708 do not have keys labeled to match
all the possible 3270 functions. Therefore, you sometimes must press two keys to
cause one function (for example, pressing ESC then 1 invokes the PFI function on
many of the supported terminals.)TI
The keyboard map defined for your terminal type describes the function the 3708
associates with a particular key sequence, and it tells you which keys on the
keyboard to press to execute each function.
Note:
The keyboard maps are found in Appendix C. Your system administrator
can obtain, for each terminal type, a reference card that contains the appropriate
keyboard map. These cards fold so that they can stand next to your terminal to be
used as a convenient reference.
Terminal Controlled Keys
3270 Functions
Your terminal may provide typematic operation for some or all keys on the
keyboard. (When a typematic key is pressed, its function is repeated as long as the
key remains pressed.) See your terminal manual for details. Also, your terminal
may have keys such as SHIFT and LOCK. You should refer to the documentation
for the terminal for a description of how it supports them. The 3708 does not
change the function of these keys.
This section describes the functions the 3708 associates with each of the keys on the
keyboard of a 3270 terminal.
• Cursor Movement functions (Cursor Up, Cursor Down, Cursor Right, and Cursor
Left).
This set of four functions moves the cursor one location at a time into any
character location. Using these functions, the cursor may be moved into any
location, including unprotected and protected fields.
The following functions are all capable of causing the cursor to wrap:
If
the cursor is located in the last position of a line and you use the cursor
right function, the cursor moves to the first position of the next line.
If
the cursor is located in the first position of a line and you use the cursor
left function, the cursor moves to the last position of the previous line.
If the cursor is located in the first line of the screen and you use the cursor
up function, the cursor moves to the last line of the screen, without changing
the column position.
If the cursor is located in the last line of the screen and you use the cursor
down function, the cursor moves to the first line of the screen, without
changing the column position.
