OpenROAD can set Alt speed keys for Button, Toggle, and Radio fields.

To position an underscore character, indicating which Alt speed key is desired, place an ampersand (&) prior to the character to be underscored when you create the label for the field, for example, "&Save" to underscore the S. You can create the label in the Frame Editor's Property Inspector for the field, or it may be created or changed dynamically by your 4GL code.

OpenROAD maintains the dynamic speed key table and associates the speed key with the field. This is done automatically for three types of fields: buttons, toggles, and radio fields.
