Abstract

The operator of a keyboard display may reorganize the layout of key functions with a software utility which runs stand-alone under the control of a processor forming part of or associated with the display. Five functions are available to the operator. These include: (1) Swapping the position of two key functions (2) Copying a key function (3) Deleting a key function (4) Deleting an entire keyboard layout (5) Placing a character from an EBCDIC I/O table onto a key position The operator may also select one of the available keypad layouts. The operator selects whether the current function takes place on all three shifts (alt, lower and upper) or only on a specific shift. Similarly, the APL keyboard designation of the key functions is modifiable.

Keyboard Definition Function

The operator of a keyboard display may reorganize the layout of key functions with a software utility which runs stand-alone under the control of a processor forming part of or associated with the display. Five functions are available to the operator. These include: (1) Swapping the position of two key functions (2) Copying a key function (3) Deleting a key function (4) Deleting an entire keyboard layout (5) Placing a character from an EBCDIC I/O table onto a key position The operator may also select one of the available keypad layouts. The operator selects whether the current function takes place on all three shifts (alt, lower and upper) or only on a specific shift. Similarly, the APL keyboard designation of the key functions is modifiable. Operation: A grid image of the keyboard is presented on the display, as shown in Fig. 1. This is called a Keyboard Definition Function (KDF) screen. At the upper left of the KDF is a selection menu for the five functions 1-5 and also alphanumeric (A), APL (B), and Exit (C) actions. These are selected by the operator, using the cursor. Then the operator selects the positions on the keyboard grid to be modified by moving the cursor to the desired key positions on the grid and pressing a selection key on the keyboard. The number of selections required is determined by the desired function (e.g., two selections for a swap or one selection for a delete). Once the selections have been made, pressing the ENTER key on the keyboard causes the change to appear on the screen. At any given time the operator sees the keyboard layout exactly as the keyboard will function with this layout in use.

Figs. 2 and 3 show a fragment of the KDF screen at successive stages of a swap operation. Usability Features: If keyboard delete (function 4) is selected by mistake, any other function selection (1, 2, 3, or 5) will cause the keyboard layout to be returned, including all changes completed during the session so far. Wherever a language independent symbol can not be used, the information is displayed in the appropriate language. For example, EXIT is shown as "SORTIE" and PF1 is shown as "FP1" when redefining a French Azerty keyboard. F...
