DEFINING A STRING
The DEFINE STRING function allows the user to assign more than one key code to a
single key. Any key that is typed in this mode is placed in the string. The user can see
the results of typing in a long box at the bottom of the screen. Note, however, that some
keys may not display what they are.
To allow the user control of entering data, five special edit functions are provided.
To access any of these functions, you first press the CONTROL and RIGHT
SHIFT keys. (This allows the user to enter any key into the buffer.)
The functions assigned to the five string edit keys are as follows:
KEY FUNCTION
RETURN End string definition.
+ symbol* Insert space in string.
- symbol* Delete cursor character.
Right Cursor Move cursor to right.
Left Cursor Move cursor to left.
*On main keyboard only.
ALT MODE
This function is a toggle (on/off) and is provided to allow the user to send 8-bit
codes to an application without the keyboard driver *'eating" the code from 80h to
FFh.
