7.5.3 User-Defined Touch Keys
You may define touch keys in arbitrary areas on the touch screen.
You may operate those touch keys by:
- Pressing them
[ 1 ] Creating a user-defined touch key with "CONSOLE.
FN3"
To create a user-defined touch key, specify the area of a touch key and a character(s) to be
displayed on the touch key, by using the extended function
"CONSOLE.FN3."
The area of a touch key can be specified with two diagonal points, "initial coordinates" and
"final coordinates."
Given below is a sample program which defines a key numbered 501 in the area specified with
initial coordinates (20, 50) and final coordinates (180, 100) and displays the character string
"ABCDE" in standard-size font in ANK quadruple.

KEYNO%=501 ’User-defined touch key numbered 501

- User-defined touch keys may be assigned #501 through #550.
- You may assign a desired character string (up to two characters) or a single control code to a
user-defined touch key.
